Jana's son had a growth spurt that started at age 10 and continued until he was 17 years old. he grew from 5'3"to 6'1". what was his average growth per year?

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75

20
