Jada earns $7 per hour mowing her neighbors’ lawns. Andre gets paid $5 per hour for the first hour of babysitting and $8 per hour for any additional hour he babysits. What is the number of hours they both can work so that they get paid the same amount?

Answer:

3 hours

Explanation:

Let

x ----> the number of hours

y ----> the amount earned in dollars

we know that

Jada


y=7x ----> equation A

Andre


y=5+(x-1)8 ----> equation B

equate equation A and equation B


7x=5+(x-1)8

solve for x


7x=5+8x-8\\8x-7x=3\\x=3\ h

Verify

For x=3 hours

Jada


y=7x ---->
y=7(3)=\$21

Andre


y=5+(x-1)8 ---->
y=5+(3-1)8=\$21
