Rosie washes clothes for two families the first family pays her $500 more per month than the second. her total earning per month is $3200. how much does she earn from each families?

Step-by-step explanation:

We know that the total monthly payment is 3200, so if we call Pa (family A`s payment) and Pb (Family B's payment) the payments:

So if we replace Pa in the first ecuation:

then Pa+Pb=3200 => Pa= 3200-1350= $1.850

Good Luck!
