Question

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?

Answer 1

Answer:

• Family 1:  $1.850
• Family 2: $1.350

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:

• Pa+Pb=3200
• also, Pa = Pb+500

So if we replace Pa in the first ecuation:

• Pb+500+Pb=3200
• 2Pb= 3200-500
• Pb=2700/2= $1.350

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

Good Luck!
