Answer: the store pays $3.95 to the credit card company.

Step-by-step explanation:

The store must pay a credit card company $0.35 for each transaction, plus 2% of the cost of the purchase. This means that if the cost of a purchase is $x, then the total amount that the store pays to the credit card company would be

0.35 + 2/100 * x = 0.35 + 0.02x

If a customer pays for a stereo costing $180 with a credit card, then, the amount that the store pays to the credit card company would be

0.35 + 0.02 * 180 = $3.95
