Answer:she earns $104 for the 2 days
Explanation:
Total number of hours that Mei worked at the coffee shop on Saturday is 7 and 1/2 hours, converting to decimal, it becomes 7.5 hours.
Total number of hours that Mei worked at the coffee shop on Sunday is 5 and 1/2 hours, converting to decimal, it becomes 5.5 hours.
Total number of hours worked for the 2 days would be the sum of the number of hours worked on Saturday and the number of hours worked on Sunday. It becomes
7.5 + 5.5 = 13
Since Mei earns $8 for every hour she works, the total amount that she earns for the 2 days would be
8×13 = $104
