A. 13 B. 14 C. 15 D. 16 E. 17 Given Chris earned x dollars per hour for the first 40 hours worked plus 22 dollars per hour for each hour worked beyond 40 hours.
Chris worked for 48 hours.
Therefore Chris earned in 8 extra hours \(= 22*8 = $176\)
Chris earned a total of 816 dollars.
\(816 = 40x + 176\)
\(40x = 816  176 = 640\)
\(x = \frac{640}{40} = 16\). Answer (D)..._________________ Please, consider giving kudos if you find my answer helpful in any way

A. 13 B. 14 C. 15 D. 16 E. 17 \(816 = 40*x + 22*8\) Or, \(816 = 40x + 176\) Or, \(816 = 40x + 176\) Or, \(40x = 640\) Or, \(x = 16\) Thus, answer must be (D) 16

Nice question.
Here is what I did for this one =>
Number of hours => 48 => 40+8 Hence the total income => 40x+22*8 which is equal to 816
Hence 40x+22*8=816 x=16
Smash that D.

A. 13 B. 14 C. 15 D. 16 E. 17 $ x per hour  40 hours $ 22 per hour  Every subsequent hour $ 816  48 hours => 40x + 22*8 = 816 => x = 16 D is the answer.

A. 13 B. 14 C. 15 D. 16 E. 17 We can create the equation: 40x + 22(48  40) = 816 40x + 22(8) = 816 40x + 176 = 816 40x = 640 x = 16 Answer: D

Hi All, We're told that Chris earned $X per hour for the first 40 hours worked plus 22 dollars per hour for each hour worked beyond 40 hour and that Chris earned a total of 816 dollars by working 48 hours last week. We're asked for the value of x ? With the given information, we can create the following equation (and solve): 40X + 8(22) = 816 40X + 176 = 816 40X = 640 X = 16 Final Answer: GMAT assassins aren't born, they're made, Rich

A. 13 B. 14 C. 15 D. 16 E. 17 All explanations above seem to be perfect , I'm just trying to express an easy calculation below: 40 x + 22* 8 = 816 [I assume all could understand till here.] =>8(5x + 22) = 816 =>5x + 22 = 102 =>5x = 80 =>x = 16

A. 13 B. 14 C. 15 D. 16 E. 17 So we're told that he worked 48 hours in total; that means 40 regular hours and 8 overtime hours. 40 hours that is the time, and the rate per hour is X dollars per hour; so that means that the amount of work, in other words the amount of money that was saved here, is 40 times X. So 40X plus 8 times 22, and that equals an 816; basically the question just boils down to a single equation with a single unknown: what is the value of X? D : 16
