Asanji 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 at a rate of $5.30=11.1 pesos?

The correct answer is $20,38.

Step-by-step explanation:

First we must analyze the information we have.

We know that Asanji changed 42.7 pesos. We are asked to find out that value in dollars.

We are given as a reference that he changed $ 5.30 to 11.10 pesos.

Having 3 of 4 unknowns resolved, the most convenient thing would be to do a cross-multiplication:

if 5.30 dollars 11.10 pesos

       x dollars 42.7 pesos

x.11.10 = 5.30. 42.70

x. 11.10 = 226.31

x = 226.31: 11.10

x = 20,388 ..

This way we can verify that the correct answer is $ 20.38
