Question

Megan&rsquo;s regular wage at her job is p dollars per hour for the first 8 hours of work in a day plus 1.5 times her regular hourly wage for work in excess of 8 hours that day. On a given day, Megan worked for 10 hours, and her total earnings for that day were $137.50. What is Megan&rsquo;s regular hourly wage?

Accepted Answer

Choice B is correct. Since p represents Megan&rsquo;s regular pay per hour, 1.5 p represents the pay per hour in excess of 8 hours. Since Megan worked for 10 hours, she must have been paid p dollars per hour for 8 of the hours plus 1.5 p dollars per hour for the remaining 2 hours. Therefore, since Megan earned $137.50 for the 10 hours, the situation can be represented by the equation 137.5 = 8 p + 2(1.5) p. Distributing the 2 in the equation gives 137.5 = 8 p + 3 p , and combining like terms gives 137.5 = 11 p . Dividing both sides by 11 gives p = 12.5. Therefore, Megan&rsquo;s regular wage is $12.50. Choices A and C are incorrect and may be the result of calculation errors. Choice D is incorrect and may result from finding the average hourly wage that Megan earned for the 10 hours of work.
