Sagot :
Answer:
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
