Question

Jennifer earns $5.50 an hour for babysitting.edward earns 1.8 times as much for mowing lawns.explain how you can tell whose hourly rate is higher without calculating.then find how many hours each one has to work to make at least $50.00

Answer 1

$5.50 * 1.8 = $9.90 (Edward)

$50 / $5.50 = 9.09 rounded to make 10 hours (Jennifer)
$50 / $9.90 = 5.05 rounded to make 6 hours (Edward)
so Jennifer needs 10 hours
Edward needs 6 hours
