Since 1 US Dollar is equal to 789.88 Chilean Pesos, we could say that n United States Dollars are equal to 789.88 times n Chilean Pesos. In other words, we could use the following formula:
Chilean Pesos = United States Dollars x 789.88
For example, let's say that we want to convert 2.0 United States Dollars to Chilean Pesos. Then, we just replace United States Dollars in the abovementioned formula with 2.0:
Chilean Pesos = 2.0 x 789.88
That is, 2.0 United States Dollars are equal to 1579.76 Chilean Pesos.
