Emma has been planting young trees in her garden. The maple tree that is 35 inches tall is growing 3 inches per month, whereas the oak tree that is 40 inches tall is growing 2 inches per month. In a few months, the two trees will be the same height. What will that height be? How long will that take?

Let x be the number of months.

 

35 + 3x = 40 + 2x

3x = 5 + 2x

x = 5

 

It will take months for the trees to be the same height, which is 35 + 3(5) = 50 inches tall.
