Answer: I hope this answers this for you!
$19,125
Explanation:
Well, this can be solved by first of all finding out the tax and subtracting it from his salary, or you can find out directly how much money he has left.
Way 1 (Subtract the tax from total)
15% = 0.15
22,500*0.15 = 3,375
22,500-3,375 = 19,125
Way 2 (Find the % left by using a %)
100% - 15% = 85%
85% = 0.85
22,500*0.85 = 19,125
