8. Odessa Dilulo demonstrates home fire alarm systems. She is paid $10.00 per demonstration for the first 10 demonstrations given during a week
and $15.50 for each demonstration over 10. Also, for every sale, she gets
a bonus of $15.00. What is her commission for a week in which she gives
18 demonstrations and makes 6 sales?

$314

Step-by-step explanation:

1. She has 18 demonstrations, so she got $10 for each of the first 10 to equal $100.

2. She got 8 demonstrations after those 10. For each of those, she gets $15.50. $15.50x8=$124.

3. She had 6 sales. Every sale is $15. $15x6=$90

4. $100+$124+$90 =$314
