5. Write a pseudocode statement that declares the variable cost so it can hold real number.
• Floating-point variable cost
6. Write a pseudocode statement that declares the variable total so it can hold integer. Initialize the variable with the value 0.
• Declare Real price = 99.95
• Display “the original price.’
• Input item original price
• Display “price”
7. Write a pseudocode statement that assigns the value 27 to the variable count.
• Count:=27
8. Write a pseudocode statement that assigns the sum of 10 and 14 to the variable total.
• Set total = 10+14
9. Write a psudocode statement that subtracts the variable downPayment from the variable total and assign the results for the variable due.
• Set due = total – downPayment
10. Write a psuedocode statement that multiplies the variable subtotal by .15 and assign the result to the variable totalFee.
• Declare Int subtotal
• Declare Int totalFee
• Declare Int taxTotal = .15
• Set totalFee = subtotal * taxTotal
