the exchange rate of US dollars to Bolivianos is $1 to 6.91 Bolivianos. if an item in the Bolivian market costs 482 bolivianos, how many US dollars does it cost?

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
