Answer:
$23,648.93
Explanation:
The tax is 7.5% of $21,999, so is ...
0.075 × $21,999 = $1649.93
Adding that to the selling price, we get the amount you would pay:
$21,999 + 1649.93 = $23,648.93
_____
It can be faster and easier to multiply the selling price by a factor that includes the tax:
21,999 + 21,999×0.075
= 21,999×1.075 = 23,648.925 which rounds to 23,648.93
