Question

6. Joe and Lisa are raising money for charity. Joe raised 4 more than three times as much as Lisa. If they

raised $848 altogether, how much did each person raise?

Answer 1

Lisa = $169.60; Joe = $678.40

Explanation:

We can create a system of equations to find how much money Joe and Lisa raised individually.

Since Joe raised 4 times as much as Lisa, we have J = 4L

And since 848 is the sum of Lisa and Joe's money together, we have J + L = 848

`J=4L\\J+L=848\\\\4L+L=848\\5L=848\\L=169.60\\\\J+169.60=848\\J=678.40`
