At their last babysitting gig, Zainab made $44 for 8 hours of work and Keziah made $47.25 in 9 hours. Each girl charges a different hourly rate. For a 10 hour job, which girl will make more money? How much more?
44/8 * 10 = ____
47.25/9 * 10 = ____
which is greater?
the first one?
To find out which girl will make more money for a 10-hour job and how much more, we need to calculate their hourly rates.
To find Zainab's hourly rate, we can divide the amount she made ($44) by the number of hours she worked (8 hours):
Zainab's hourly rate = $44 ÷ 8 hours = $5.50/hour
To find Keziah's hourly rate, we can divide the amount she made ($47.25) by the number of hours she worked (9 hours):
Keziah's hourly rate = $47.25 ÷ 9 hours = $5.25/hour
Now that we have their hourly rates, we can calculate how much each girl will make for a 10-hour job.
For Zainab:
Zainab's earnings for a 10-hour job = Zainab's hourly rate ($5.50/hour) × 10 hours = $55
For Keziah:
Keziah's earnings for a 10-hour job = Keziah's hourly rate ($5.25/hour) × 10 hours = $52.50
So, for a 10-hour job, Zainab will make more money ($55) compared to Keziah ($52.50). Zainab will make $55 - $52.50 = $2.50 more than Keziah.
