Answer 1

On December 13, 2007, 71.33 pesos was worth approximately 772.60 dollars, and 130.45 dollars was worth approximately 12.03 pesos.

Step-by-step explanation:

(a) To find out how many dollars 71.33 pesos is worth, we can set up a proportion using the exchange rate:

10.83 pesos = 1 dollar

x pesos = 71.33 dollars

Cross-multiplying, we get:

x = (71.33 dollars)(10.83 pesos) = 772.5989 pesos

Rounded to the nearest hundredth of a dollar, 71.33 pesos is worth approximately 772.60 dollars.

(b) To find out how many pesos 130.45 dollars is worth, we can set up a proportion using the inverse of the exchange rate:

1 dollar = 10.83 pesos

x dollars = 130.45 pesos

Cross-multiplying, we get:

x = (130.45 pesos)(1 dollar/10.83 pesos) = 12.0265 dollars

Rounded to the nearest hundredth of a peso, 130.45 dollars is worth approximately 12.03 pesos.
