Question

Sophia has a total of 32 pictures. She has 17 pictures that are 5 millimeters wide. The rest of her pictures are 6 millimeters wide. What is the value of w, the total width of all of Sophia's pictures?

Answer 1

32-17 = 15

w = 17*5 + 15*6

by the way I bet they mean centimeters not millimeters.
