hours spend on days other than Sunday = 408 = 32 hourse spend on Sunday = 8
32*8.5 + 8*17 16*17 + 8*17 17* (8+16) 17* (24) = 408

Rene earns $8.50 per hour on days other than Sundays and twice that rate on Sundays. Last week she worked a total of 40 hours, including 8 hours on Sunday.What were her earnings for the week?
(A) $272 (B) $340 (C) $398 (D) $408 (E) $476
Given that Rene worked 40  8 = 32 hrs @ $8.50/hour on weekdays except Sunday & Rene worked for 8 hrs @ $17.00/hr on Sunday So, total earnings for the week was 32* $8.5 + 8 * $17 = 16*$17 + 8 * $17= 24*$17 = $408
Answer: (D)

(A) $272 (B) $340 (C) $398 (D) $408 (E) $476 1 hr of Sunday work = 2 hrs of regular day work. Total of 48 hrs (32 hrs. MonSat + 16 equivalent hrs. on Sunday) at $8.50/hour 48*8.50=408 Only one calculation this way.

I hope a one line solution for this question is Total amount($)=Time(in Hour)* Wage (in $/hour) 8*17+32*8.5=136+272=408 $
Answer is D

Last week she worked a total of 40 hours, including 8 hours on Sunday.What were her earnings for the week? (A) $272 (B) $340 (C) $398 (D) $408 (E) $476 Basic calculation is 32 * 8.5 and 8*17. Lets say you are in hurry and you have 30 secs on the clock. we can calculate 32 * 17/2 = 16 * 17 and 8 * 17 . 6*7 ends in 2 and 8*7 ends in 6 so the answer ends in 8. Eliminate A/B/E. You just increased the probability by 30% points to 50%. Take a pick and move on. So try not to click randomly in case of time pressure. Take a calculated guess, doesn't take more than 30 secs including reading the question. For proper calculation: 16*17 + 8*17 = 256 + 16 + 80 + 56 = 408  Option D)

Option D. Total wages=Total hours * hourly wage rate =>32 * 8.50 + 8 * 17 What I did to solve this is: 32 * 8 + 32 *0.5 +17 * 8 16 + (32+17)*8 16 + 49 * 8 16 + 400  8 408

1 step calculation can be: Since working on Sunday is equal to double pay i.e. 8hrs = 16hr pay total hours =40 Take it as 48hrs total into $8.5 = $408

1. Total Hours  Sunday Hours = 40  8 = 32 2. 32 x $8.50 = $272.00 3. 8.5 x 2 = $17.00/hour on Sunday 4. $17.00 x 8 = $136.00 5. $272.00 + $136.00 = $408.00
Answer is (D) $408
