The Epson Picturemate

Question

The Epson Picture mate compact photo printer can print a 4-inch by 6-inch photo in 37 seconds, and the Epson Artisan 810 all-in-one printer can printer can print the same size photo in 10 seconds. How much longer would it take the Epson picture mate show to print twelve 4-inch by 6-inch photos?

Answer 1

First you want to calculate how long it would take to print using the picture mate printer, so you multiply 37 * 12 because it takes 37 second for one picture and there are 12 prints. So 37* 12= 144. then for the artisan printer it takes 10 seconds for the one print and there are 12 prints, so you multiply 12* 10 which equals 120. And the question for the problem is asking you to find the difference between the two printers, so you are going to need to subtract. So you subtract 144-120. So the answer is 324 seconds.
