Answer:
8 dollars per hour
Step-by-step explanation:
You make 92 a week
20 of that is from your allowance
92-20 = 72
72 is from your part time job
You work for 3 hours on Friday and 6 hours on Saturday, for a total of 3+6 = 9 hours
Take the amount of money earned and divide by the number of hours to determine the money earned per hour
72/9 = 8 dollars per hour
The answer is 7x/12 - 1/2. Its the first option in your picture. Hope this helps .
