Acar originally priced at $8,900 is on sale at 15% off. if the sales tax rate is 8.25%, what is the sale price of the car?

8189.11

Step-by-step explanation:

If 8900 is 100% and we need to find 15%  we would multiply 8900 and 15 then divide by 100 and that equal 1335 so we would then subtract 1335 from 8900 because it is 15% off, which equals 7565, so now 7565 is 100% and we need to add the 8.25% tax, so we multiply 7565 and 8.25 then divide by 100 which equals 625.11 then we add 7565 and 625.11 which equals 8189.11

answer: .64
