Answer:
Movie Rental B is better to buy. It's cheaper by .75 cents.
Explanation:
Solving Movie Rental A
To find the unit rate of this one, we divide the dollars and the rentals.
So, 15 ÷ 3 = 5
Unit Rate for Movie Rental A is 5
Solving Movie Rental B
Same as Movie Rental A, divide the dollars and the Rentals.
8.5 ÷ 2 = 4.25
The number with the less amount is cheaper so
4.25 is less than 5
