Answer 2

The customer orders approximately 12 refills with the reusable mug.

Step-by-step explanation:

To find the number of refills the customer orders, we need to subtract the cost of the reusable mug from the total amount spent. This will give us the total spent on refills.

To calculate the number of refills, we can divide this total by the cost of each refill, which is $0.99.

So the formula to calculate the number of refills is:

Number of refills = (Total amount spent - Cost of mug) / Cost per refill

Using the given information, we can substitute the values into the formula:

Number of refills = ($21.52 - $8.65) / $0.99

This simplifies to:

Number of refills ≈ 12

The customer orders approximately 12 refills with the reusable mug.
