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

During the week Rene worked a total of 40 - 8 = 32 hours at a rate of $8.5 per hour. On Sunday she worked 8 hours at a rate of $8.50*2 = $17.00 per hour.

Therefore her total earnings for the week were 32*8.50 + 8*17 = $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

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

1 hr of Sunday work = 2 hrs of regular day work. Total of 48 hrs (32 hrs. Mon-Sat + 16 equivalent hrs. on Sunday) at $8.50/hour

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.
