Answer

Find out the number of refills keith bought and write equation for it .

To prove

Let us assume that the number of refills be x .

a restaurant sells a coffee refill mug for $6.75.

Each refill costs $1.25

Last month keith spent $31.75 on a mug and refills .

Than the equation becomes

6.75 + 1.25 × x = 31.75

6.75 + 1.25x = 31.75

1.25x = 31.75 - 6.75

1.25x = 25

x = 20

Therefore the  number of refills keith bought be 20 .
