Hi,
For each Australia dollar, Amy receives 80 United States cents, I.e $A1 = US80c. She wants $US600 for a trip, how much should she receive in Australian dollars?
A)$480 B)$800 C)$750 (D)$720
For each Australian dollar, Amy receives 4/5 U.S. dollars. Letting x be the number of Australian dollars, we can multiply this by 4/5 and equate to 600 to find the number of Australian dollars that is equivalent to 600 U.S. dollars.
Now solve for x.
