Answer:
He earms $5.50 per hour of baby sitting.
Step-by-step explanation:
The unit rate is how much he earns per hour of babysitting. To find this we have to figure out what to divide from 5 in order to get 1.
5 ÷ 5 = 1
So we know we have to divide 5 by 5 to get 1. This means that we have to divide 27.50 by 5.
27.50 ÷ 5 = 5.5
So this means he makes $5.50 per hour of babysitting. To check this, multiply 5.50 by 5.
5.50 x 5 = 27.50
He earns $27.50 for 5 hours of babysitting, so this is correct.
