Find the final cost of a $279 Nintendo Switch that is on sale for 15% off and you have to pay 8.25% sales tax.

Answer: $256.61

Solution:

Step 1. Find 15% of 279 then subtract from 279, so, 279-41.85=237.15

Step 2. We find the 8.25 sales tax then add it to the cost of the 237.15

So we add: 237.15+19.56=256.61
