Navin from Mauritius, Luka from Croatia, and Ian from Botswana are chatting in the lobby of a youth hostel discussing their part-time jobs. They learn that Navin makes 160 rupee per hour, Luka makes 25 kuna per hour, and Ian makes 34 pula per hour. If one US dollar is equivalent to 32.35 Mauritius rupee, 5.18 Croatian kuna, and 6.95 Botswana pula, who would earn the most after working an eight-hour day?

1. Since the US dollar is the point of reference for all 3 currencies, just convert all currencies to US dollars. Then it is easy to compare

If will do the first you do the other two.
32.35 Mauritius rupee = \$1.00
1 ruppee = 1.00/32.35 dollars
160 ruppee = 16(1/32.35)
= 16/32.35 dollars or \$0.49 , notice the very last calculation.

3. Use the same method for the other two outlined by Reiny and compare the results.
However, I think if 1 ruppee = 1.00/32.35 dollars
then 160 ruppee = 160(1/32.35) leading to \$4.90
