She already has 32$. And makes 4$ every hour of mowing lawns.

4 + 4 + 4 + 4 + 4 + 4 + 4 = 30 = 4 x 7 which equals 30



Joan needs to work 7 hours in total to get 28$.

Joan has 32$. And makes 4$ every hour of mowing lawns.

60-32=28.

So what we will do to solve this problem is multiply 7 by 4.

7x4= 28.

32+28=60.

This means that Joan needs to work 7 hours in total to earn $28.
