Question

You have a job which pays double-time when working more than 40 hours for a week. Last week you worked 55 hours and earned $840. What is your regular pay rate?​

Answer 1

$12/hour

Explanation:

f(x) = px for x ≤ 40 hours

f(x) = px + 2py if you do overtime work

y = the over time

p = regular pay

840 = 40p + 2(15)p

840 = 40p + 30p

840 = 70p

p = 840/70 = $ 12/hour
