Caroline’s Coffee Shop sells a refill mug for $8.95. Each refill costs $1.50. Last month Sean spent $26.95 on a mug and refills. How many refills did he buy?

Alright! First you'd have to subtract the flat fee of the mug which is $8.95, then you'd have to divide by the rate which is $1.50. Your equation would be:

(26.95 - 8.95) ÷ 1.50 = r

Then you solve using your head.. lol.

(26.95 - 8.95) = 18.

(18 ÷ 1.50) = 12.

R = 12.

the answer is b.)

< 1=< 2

- (2, -7)

- lines r and s and lines t and u must be parallel
