Jamies allowance is 5/7 of cathy's. If jamie gets 550 pesos, how much is the difference between their allowances?

Answer 1

Let's assume that Cathy's allowance is C pesos

Therefore Jamie's allowance is 5/7 x C

If Jamie gets 550 pesos, then 5/7 x C = 550

When we solve for C (Cathy's allowance), we get 5C = 3850, therefore C = 770

So now we know that Cathy's allowance is 770 pesos and

Jamies allowance is 550 pesos

We are asked what the difference is between them is,

770 - 550

= 220 pesos
