Jose has $20 more than sarah. their combined mobey totals $90. write and solve an algebric model to determine the amount of money each person has.

Let S= the amount of money Sarah has.

Let J= the amount of money Jose has

J= S+20

J+S=90

But we also know that J can equal S+20

So,

S+20+S=90

2S+20=90

2S=70

S=35

So Sarah has $35, and Jose has $35+$20, so he has 55$
