Question

Deborah has two paintings in her portfolio and paints three more each week.Kai has twelve paintings in her portfolio and paints two more each week.After how many weeks will Deborah and Kai have the same number of paintings ?

Answer 1

Well, we can set up these equations like this-
Deborah- 2+3w
Kai- 12+2w
w=number of weeks that pass
Now, we set them equal to each other:
2+3w=12+2w

Solve for w
2-12=2w-3w
-10 = -1w
w = 10
10 weeks. Hope this helped!
