Joe went shopping for a guitar in Fairfax. He purchased one originally priced at $240 but discounted 80%. If sales tax in Fairfax is 9.25%, what was the total cost?

$52.44

Step-by-step explanation:

Decimal = Percentage / 100

If 240 was discounted 80%, you would deduct 80% of 240

80% of 240 = 0.8*240 = 192

20% is left, so 240 - 192 = 48

Now, we have to find 9.25% of 48

48 *0.0925 = 4.44

The tax was $4.44

48 + 4.44 = 52.44

The total cost was $52.44

Hope this helps :)

Have a good day!
