Hello! So Ms. Donaldson earned $18.80 an hour for the first 40 hours and earns 1.5 times that amount for each hour over 40 hours. First, let's find the amount earned overtime. 18.80 * 1.5 is 28.2. $28.20 is earned for each hour overtime. She worked 45.5 hours last week. Let's multiply 18.8 by 40 to find the amount for those hours. 18.8 * 40 is 752. $752 were earned. As we can see, 5.5 hours of overtime work were done. Now, multiply 28.2 by 5.5 to find the amount made from overtime. 28.2 * 5.5 is 155.1. $155.10 were made overtime. Now, let's add the amounts together. 752 + 155.10 is 907.1. There. Ms. Donaldson earned $907.10 last week.

Ibelieve the answer would be 7, 13, 23
