Before leaving to visit Mexico, Levant traded 270 American dollars and received 3,000 Mexican pesos. When he returned from Mexico, he had 100 pesos left.
How much will he receive when he exchanges these pesos for dollars?
Answer:
9 dollars
Step-by-step explanation:
To find the amount that Levant will receive when he exchanges these pesos for dollars, you can use a rule of three using the information provided:
