Step-by-step explanation:
Let's write the function equation for Eric's earnings based on the given information.
Let:
E(H) be Eric's earnings in dollars.
H be the number of hours Eric works per week.
Now, we need to define the function E(H) based on the number of hours worked:
E(H) = {
0, if H < 10,
10 * (H - 9), if 10 <= H <= 25,
10 * 16, if H > 25
}
Step-by-step explanation:
If H < 10 (less than 10 hours), his earnings will be 0 since he needs to work a minimum of 10 hours to get paid.
If 10 <= H <= 25 (between 10 and 25 hours, inclusive), he will be paid for the number of full hours worked at his hourly wage ($12 per hour), minus the initial 9 hours (to account for the 1st hour when he didn't get a raise). So, he will receive $10 for each hour worked above 9 hours.
If H > 25 (more than 25 hours), he will be paid for 16 hours at his hourly wage ($12 per hour), as his boss increased his work hours to a maximum of 25 per week.
This function equation accounts for the restrictions that Eric needs to work a full hour to get paid, and the boss has increased his work hours while giving him a $2 raise.
