On a trip to Reykjavk, Geri orders a meal for 2370 ISK. What is the equivalent price in U. S. dollars and cents?
Enter your answer in the form $ab.cd, where a,b,c, and d are replaced by appropriate digits.
this is a simple ratios and proportions question
since 1 us dollar= 120 isk, all you need to do is to divide these two numbers because you are trying to find U.S dollars
so 2370 isk/120isk = 19.75
$19.75 where a = 1, b= 9, c= 7, and d=5
