Question 1019315: Javier works in a photo lab and needs to make a reduced copy of a photograph that is 8 inches long. The customer wants the copy to have a length of 4.5 inches. Each time he presses the reduce button on the copier, the copy is reduced by 12%. Javier and his boss had an argument, because Javier claimed that pressing the button 5 times would be enough to fulfill the customer's request. His boss said that pressing the button 5 times would result in a length less than the desired 4.5 inches. Which of the following conclusions can be made?
Javier is correct and he should press the button five times
Javier's boss is correct and he should press the button five times.
Javier is correct and he should not press the button five times.
Javier's boss is correct and he should not press the button five times.

Question 1019486: The Hybrid-Only Car Rental agency uses the function
f(x) = 26
for any daily use of a car up to and including 220 miles. For driving more than 220 miles per day, it uses the function
g(x) = 26 + 0.16(x − 220)
to determine the charges. How much would the company charge for daily driving of 120 miles? of 260 miles? of 330 miles? of 400 miles?
Your help is much appreciated.
