<h2>
6.75+1.25x=31.75</h2>
Step-by-step explanation:
let x be the number of refils
also given is that the cost of one refill is $1.25
hence the total refil will be 1.25x
given that the cost of a mug is $6.75
6.75+1.25x=31.75
therefore the expression that can be used to solve for the number of refills is
6.75+1.25x=31.75
