Jorge took a trip to Mexico.Upon leaving he decided to convert all of his pesos back into dollars.How many dollars did he receive if he exchanged 42.7 pesos a rate of $5.30 = 11.1 prsos?
5.30/11.1 = x/42.7
11.1x = 226.31
x = $20.39
But is that right for algebra 1? Just wondering
I've been using proportions since 8th grade.
Another way to figure this problem is this:
5.30/11.1 = $0.477 per peso
0.477 * 42.7 = $20.39
