Manny has two part-time jobs. She earns $21.00 per hour (a) working as an aerobics instructor, and $12.50 per hour (s) working at the skating rink. Her earnings are represented by the expression . How much money will she earn working 4 hours as an aerobics instructor and 8 hours at the skating rink?

Question

$ Remember to include the dollars and cents. If you do not include the dollars and cents, this problem will be counted as incorrect.

Answer 1

To calculate Manny's total earnings from both jobs, we can use the hourly rates and the number of hours worked:

1. Earnings from aerobics instruction: \[ \text{Earnings from aerobics instructor} = 21.00 , \text{(per hour)} \times 4 , \text{(hours)} = 84.00 \]

2. Earnings from working at the skating rink: \[ \text{Earnings from skating rink} = 12.50 , \text{(per hour)} \times 8 , \text{(hours)} = 100.00 \]

Now, we can sum the two amounts to find her total earnings: \[ \text{Total earnings} = 84.00 + 100.00 = 184.00 \]

Thus, Manny will earn $184.00 from both jobs combined.
