Answer :

each case contains 12 paper rolls.

It is given that total number of rolls paper towels is y

and x is the total number of the case,

then y can be represented in term of x

y = 12x

but it is given that 4 rolls are purchased by the customer, we will subtract 4 from total

so now the equation for the total rolls will be,

y = 12x - 4

so it is the equation for total rolls remaining in the store.

And the correct answer is option A.
