Sonia is traveling to Mexico and wants to change her US dollars into pesos. A) Her friend who just returned from Mexico says that he received 3061 pesos for $150. If the exchange rate is the same when Sonia travels, how many pesos would she receive if she exchanges $500? Round to nearest whole peso.

B) During her trip, Sonia spends 7500 pesos. How many US dollars does she receive when she exchanges her remaining pesos? Round to the nearest penny.

A) 10203

B) 132.46

Step-by-step explanation:

1)Using the 3061 pesos for the $150, and x pesos for $500

, from there you can cross-multiply to get

150x=1530500, and you divide by 150 to get

x=10203.33, and you round to the nearest whole number to get

x=10203

2)Using the 3060 pesos for the $150, and (10203-7500) pesos for $x.

10203-7500=2703

, from there you cross-multiply to get

3061x=405450, and you divide by 3061 to get

x=132.4567, and you round to the nearest penny(nearest hundredth) to get

x=132.46
