Question

Nadia charges $7.50 an hour for babysitting. She babysits 18.5 hours the first week of the month and 20 hour the second week of the month. Suppose Nadia raises her rate by $0.75 an hour. How many hours would she need to work to earn the same amount of money she made in the first two weeks of the month? Explain.

Answer 1

$7.50 * 18.5 hrs = $138.75

$7.50 * 20 hrs = $150

138.75 + 150 = 288.75

She raises the price by ¢0.75

So now it is $8.25 per hour

(I guessed on a calculator and got it right)

Multiply 8.25 by 35 and you get 288.75

Your answer is 35
