Paige earned $15.50 per hour. She received an 18% raise. If Paige worked 10 hours at her new salary. How much did Paige earn?
BaLLatris [955]
First, figure out the new salary. To do this, multiply 15.50 and 0.18. This is 2.79. Add this to 15.50.

15.50 + 2.79=18.29

Therefore, $18.29 is her hourly pay.

To find how much money she earns in 10 hours, multiply this pay per hour (18.29) times the hours worked (10).

18.29 x 10

182.9

This means that Paige earns $182.90 for working 10 hours.

Hope this helps! Please comment if you need any more explanation and I’ll get back to you ASAP :)
