Answers:

  • Zainab made more money
  • She made $2.50 more

=======================================================

Explanation:

To find the hourly rate, we divide the money made over the number of hours.

  • Zainab's hourly rate = 44/8 = $5.50 per hour
  • Keziah's hourly rate = 47.25/9 = $5.25 per hour

Then we'll multiply each of these results by 10 to figure out how much they made over the 10 hours

  • Zainab: 5.50*10 = 55 dollars
  • Keziah: 5.25*10 = 52.50 dollars

We see that Zainab made more money and she made 55-52.5 = 2.50 dollars more.
