Answer:


f(x) = 15x - 200

Explanation:

Given


Earnings = \$10 per hour for 40 hours, weekly


Additional\ Hour = \$15 per hour over 40 hours, weekly

Required

Determine f(x)

From the question, we have that

x represents hours worked

Earnings in 40 hours is: 40 * 10 = $400

Hours over 40 will be: x - 40

So, earnings during this time will be: (x - 40) * 15

Total earnings is:


f(x) = 400 + (x - 40) * 15


f(x) = 400 + 15x - 600


f(x) = 15x - 600 + 400


f(x) = 15x - 200
