Section 8.1
33. a. A set of four ordered pairs in which each of the least corrupt countries corresponds to a corruption rating is; (Iceland,9.7),Finland,9.6),(New Zealand,9.6),(Denmark,9.5). b. The relation in part (a) is a function because each country corresponds to only one corruption rating. c. A set of four ordered pairs in which corruption ratings for the least corrupt countries correspond to countries; (9.7,Iceland),(9.6,Finland),(9.6,New Zealand),(9.5,Denmark) d. The relation in part (c) is a not a function because 9.6 corresponds to both Finland and New Zealand.
Section 8.2
47. a. f(x)=.013(80)+56.46=57.50
F(80) represents (80,57.5) on the graph. This states that in 1980, the average temp. was 57.50 degrees. b. The graph shows 57.50 as the average temp. in 1980 which is overestimated by .10 degrees as the average temp in 1980 was actually 57.40 degrees.
49. a. f(x) = 1.27(50)+305=368.5 (50,367.5) f50 on the graph represents the average atmospheric concentration of carbon dioxide in parts per million as 368.5 in the year 2000.
b. g(x)=.01(50)^2+.65(50)+310=367.50 parts per million was the average carbon dioxide concentration in 2000.
c. The quadratic function
51. f(x)=.4(20)^2-36(20)+1000 (20,440) .4(400)-720+1000 160-720+1000 There are 440 accidents per 50 miles for 20 year old drivers.
53. (45,190) The value of x is 45 and the value of y is 190 when the graph is at its lowest point. .4(45)^2-36(45)+1000 .4(2025)-1620+1000 810-1620+1000=190
The minimum number of accidents occurs with 45 year old drivers at 190 accidents per 50 million miles driven.

55. f3 on this graph is (3,.78). This represents that it will cost $0.78 to mail a first class letter weighing 3 ounces.
57. It will cost $0.61 to mail a first class letter weighing 1.5 ounces.
Section 8.3
63. a. (M+F)(X) (1.54x+114.6)+(1.48x+120.6) 3.02x+235.2 b. 3.02(10)+235.2 265.4 The book shows the answer as 295.6 but I keep getting 265.4 c. the results from part B are underestimated by 32.6mm.
65. a. (M/F)(X)= 1.54x+114.6 ---------------- 1.48x+120.6

(M/F)(5)= 1.54(5)+114.6 122.30 ----------------- --------- 1.48(5)+120.6 128 b. 122.30/128 = .955
c. This is an underestimated number. The actual ratio of men vs women in 2000 is .965.
Section 8.4
61. a. f reflects the discount off the original price and g reflects the percentage of the original price, in this case g is 75% of the original price. b. (fog)(x)=f(g(x))= x-400 .75x-400 c. (gof)(x)=.75(x-400) d. I have to say .75x-400 and .75x-400 should be the same. e. x-400 y=.75x-400 x=.75y-400 400+ x=.75y-400+400 X+400/.75=Y F^1(x)=x+400
F^1 represents the original sale price of the item while x represents the price after the $400 discount.

...Chapter 8 Individual Income Tax Computation and Tax Credits SOLUTIONS MANUAL Discussion Questions 1. [LO 1] What is a tax bracket? What is the relationship between filing status and the width of the tax brackets in the tax rate schedule? A tax bracket is a range of taxable income that is taxed at a specified tax rate. Because only the income in the particular range is taxed at the specified rate, tax brackets are often referred to as marginal tax brackets or marginal tax rates. The level and width of the brackets depend on the taxpayer’s filing status. The tax rate schedules include seven tax rate brackets. The rates for these brackets are 10%, 15%, 25%, 28%, 33%, 35%, and 39.6%. In general, the tax brackets are widest for Married filing jointly (for example, more income is taxed at 10%), followed by Head of household, Single, and then Married filing separately (the brackets for Married filing separately are exactly one-half the width of the brackets for Married filing jointly, and the width of the 10% and 15% brackets for Single and Married filing separately are the same). 2. [LO 1] In 2014, for a taxpayer with $50,000 of taxable income, without doing any actual computations, which filing status do you expect to provide the lowest tax liability?

...Solutions to Questions 8-1 Activity-based costing differs from tradi-tional costing systems in a number of ways. In activity-based costing, nonmanufacturing as well as manufacturing costs may be assigned to products. And, some manufacturing costs—including the costs of idle capacity—may be excluded from prod-uct costs. An activity-based costing system typically includes a number of activity cost pools, each of which has its unique measure of activity. These measures of activity often differ from the allocation bases used in traditional costing systems. 8-2 When direct labor is used as an allocation base for overhead, it is implicitly assumed that overhead cost is directly proportional to direct labor. When cost systems were originally devel-oped in the 1800s, this assumption may have been reasonably accurate. However, direct labor has declined in importance over the years while overhead has been increasing. This suggests that there is no longer a direct link between the level of direct labor and overhead. Indeed, when a company automates, direct labor is replaced by machines; a decrease in direct labor is accompa-nied by an increase in overhead. This violates the assumption that overhead cost is directly propor-tional to direct labor. Overhead cost appears to be driven by factors such as product diversity and complexity as well as by volume, for which direct labor has served as a convenient measure. 8-3 Top managers provide leadership that is needed to properly motivate...
