Question

Alicia took a trip to Mexico. Upon leaving he decided to convert all of his Pesos back into dollars. How many dollars did she receive if he exchanged 42.7 Pesos at a rate of $5.30 = 11.1 Pesos?

Answer 1

Alicia exchanged 42.7 Pesos for US

11.1 pesos = $5.30

11.1/5.30 = 2.09/1

So for every 2.09 pesos, she gets 1 US dollar

42.7/2.09 = x US dollars
42.7/2.09 = 20.43

For exchanging 42.7 Pesos, Alicia gets US $20.43

hope this helps
