joan needs $60 for a class trip. She has $32. She can earn $4 an hour mowing lawns. How many hours must Joan to have the money she needs?

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.
