Answer: $20.70
Step-by-step explanation: He pays $20.70, follow these steps:
The formula for finding the percentage:
Whole number * part percent / 100
Plug in the numbers:
23 x 10 / 100
23 x 10 = 230
230 / 100 = $2.30
That's not all, we need to subtract $2.30 from the original amount. So:
23 - 2.30 = $20.70
After the rebate, Deon pays $20.70
He saves $2.30
I hope this helps!
