Problema Solution

While preparing to visit the United States, Greg exchanged 200 Canadian dollars for 1/5 fewer U.S dollars. After spending 3/4 of the U.S dollars, how many did he have left?

Answer provided by our tutors

200 Canadian dollars = 200 - (1/5)200 US dollars

200 Canadian dollars = 160 US dollars

After spending 3/4 means that 1 - 3/4 = 1/4 is left or:

(1/4)*160 = 40 US dollars

Greg has 40 US dollars left.
