Question

Marisa and Lisa earned a total of $65 babysitting during the month of November. Marisa earned $5 more than 1/2 of what Lisa earned. How much did they each earn?

Answer 1

Marisa earned `$ 25` and Lisa earned `$ 40`

Explanation:

Let Marisa earned `$M` and Lisa earned `$L ; M+L=65`

By condition given `M =1/2*L +5 or 1/2*L = (M-5) or L = 2M - 10`

Putting `L = 2M - 10` in

`M +L = 65 or M + 2M -10 = 65 or 3M = 65+10 or M= 75/3 =$25 :. L=65 -25 =$40`

Marisa earned `$ 25` and Lisa earned `$ 40` [Ans]
