Question: 178

13. While on vacation in Morocco, Erik decided to splurge on a fancy hotel that cost 2,000 Moroccan dirhams per night. If he stayed in that particular hotel for three nights, but his bank only lets him withdraw $200 at a time, how many visits to the ATM must Erik have made in order to cover the cost of his hotel stay?

(Note: 1 Moroccan dirham = $0.11)

  • A. 1
  • B. 2
  • C. 3
  • D. 4

Correct Answer: D

Explanation:

D To stay at his fancy hotel for three nights at 2,000 Moroccan dirhams per night, Erik will need 6,000 dirhams. Using the currency conversion rate of 1 dirham = $0.11, we can multiply 6,000 × 0.11 to determine that Erik's hotel stay will cost $660. Since his bank allows him to withdraw only $200 at a time, Erik must go to the ATM four times: (D).
