100 divided by 3 = 33 now 33 - 7 =26.
so she wrote 26 pages.
A bag of chip = 0.85, let a bag of chip be x
a bag of gatorade is 1.50, let gatorade be y
23.70 is the amount Kennedy spent in all
0.85x + 1.50y = 23.70
step 1: shows the wrong step already, because you shouldn't take out a -0.85, and y is not 0.85 either, but 1.50, so y should still have 1.76 left
so your answer should be step 1.
hope this helps
