Answer:
<u>The four employees earned $ 452.80 in total</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Hour rate = $ 8.20
Overtime hour rate = $ 2.20 extra
Regular hours = 10
Overtime hours = 3
Number of employees = 4
2. How much money did they earn in total?
Let's find out the individual pay for an employee and then we'll calculate the pay for the 4 employees:
Individual pay = 10 * 8.20 + 3 * 10.40
Individual pay = $ 113.20
Total pay = Individual pay * 4
Total pay = 113.20 * 4
<u>Total pay = $ 452.80 </u>
