Final answer:
After subtracting the initial cost of the reusable cup, the customer spent $50 on refills. At $2 per refill, this equates to 25 refills, or 25 cups of coffee, for the month.
Step-by-step explanation:
The question involves calculating the number of coffee refills a customer gets after spending a certain amount of money. Initially, the customer spends $3 for a reusable cup, and then $2 for each refill. The total amount spent at the end of the month is $53. To find the number of refills, we need to subtract the initial cost of the reusable cup from the total amount spent and then divide the result by the cost per refill, which is $2.
Therefore, we perform the following calculations: $53 (total) - $3 (reusable cup) = $50 (total for refills). Next, we divide $50 by the $2 refill cost to get the number of refills.
$50 รท $2 = 25 refills
This means the customer was able to get 25 cups of coffee after the initial purchase of the reusable cup.
