Carson's parents have saved $12.460 and he earned a $6,500 yearly scholarship. He must cover all of the
remaining expenses with student loans. Assuming Carson

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.
