At a fast food restaurant, Anas normally works 6.25 hours per day and earns $5.60 per hour. For each hour he works in excess of 6.25 hours on a given day, he is paid 1.25 times his regular rate. If Anas works 10.25 hours on a given day, how much does he earn for that day? work = 6.25 hours salary per hour =$5.60
Total salary earned = 6.25 * 5.60 = 35

For each extra hour, rate = 1.25 * 5.60 = 7

Now total hours works = 10.25 = 6.25 + 4
So got salary at rate of 5.60/hour for initial 6.25 hours and at rate of 7/hour for last 4 hours.

Total salary = (6.25*5.6) +(4*7) = 35+28 = $63 Answer: B Kudos [?]: 109 [0], given: 66 VP Joined: 22 May 2016 Posts: 1139 Kudos [?]: 408 [0], given: 648 At a fast food restaurant, Anas normally works 6.25 hours per day and [#permalink] ### Show Tags 28 Sep 2017, 11:30 Bunuel wrote: At a fast food restaurant, Anas normally works 6.25 hours per day and earns$5.60 per hour.

A. $72 B.$63
C. $54 D.$48
E. $35 Changing every decimal into a fraction makes arithmetic easier. Factors cancel. Regular hours for a workday = 6.25 hrs = $$6\frac{1}{4} = \frac{25}{4}$$ hours Regular pay:$5.60 per hr =
$$5\frac{3}{5} = \frac{28}{5}$$ per hour

Overtime: working > 6.25 hrs

Overtime rate of pay:
1.25 times regular rate =
$$1\frac{1}{4} = \frac{5}{4} * \frac{28}{5} = \frac{28}{4} = 7$$ per hour

If Anas works 10.25 hours, how much does he earn for that day?

Extra hours worked: 10.25 - 6.25 =
4 extra hours

Earnings for extra hrs=
(Overtime rate) * (# of hours)
$$(\frac{7}{hr}) * (4 hrs) = 28$$

Earnings for regular hours =
(Regular rate) * (Regular # of hrs)
$$\frac{28}{5hrs} * \frac{25}{4}hrs = 35$$

TOTAL earnings: $28 +$35 = $63 ANSWER B Kudos [?]: 408 [0], given: 648 Target Test Prep Representative Status: Head GMAT Instructor Affiliations: Target Test Prep Joined: 04 Mar 2011 Posts: 1810 Kudos [?]: 991 [0], given: 5 Re: At a fast food restaurant, Anas normally works 6.25 hours per day and [#permalink] ### Show Tags 03 Oct 2017, 09:04 Bunuel wrote: At a fast food restaurant, Anas normally works 6.25 hours per day and earns$5.60 per hour.

A. $72 B.$63
C. $54 D.$48
E. $35 Anas’ regular rate is$5.60 and his overtime rate is (1.25)(5.60), or \$7. We can create the following equation:

6.25(5.6) + 4(1.25 x 5.6)

35 + 4(7) = 35 + 28 = 63
