On a trip, you had to change your money from dollars to British pounds. You got 560 pounds for 800 dollars. Which is a unit rate that describes the exchange?
1 3/5 pounds per dollar
0.625 pounds per dollar
1 3/7 pounds per dollar
0.7 pound per dollar
If we got 560 pounds for 800 dollars and x pounds for 1 dollar, this means that x = 560*1/800 <=> x = 56/80. Performing the calulation we get that x = 0.7 . So the right answer is the final one.
