Sarah has three more than four times the money that Jessica has. Together they have $72. How
much does each person have?

Respuesta :

Answer:

Jessica has $13,80 and Sarah has $58.20.

Step-by-step explanation:

Let j be the amount of money that Jessica has.

Let s be the amount of money that Sarah has.

s + j = 72

Since Sarah has 3 more than 4 times what Jessica has...

s = 4j + 3

So 4j + 3 + j = 72

5j = 69

j = 13.8

So Jessica has $13,80.

Therefore Sarah has $58.20.
