Basically you have to complete about 4 steps.

First you take 650.00 and multiply it by .10 or divide it by 10… Which equals 65.00.

Then you subtract the 65.00 from the 650.00… Which equals 585.00.

Then you take 585.00 and mutliply it by .10 or divide it by 10.. Which equals 58.50.

Then you subtract the 58.50 from 585.00… which equals 526.50

Final Price = $ 526.50

Discount = 65.00 + 58.50 = $ 122.50

P – 0.10P = 0.90P

0.90P – 0.09P = 0.81P

if you plug in P = 650, you should get the numbers.

for the discount, we take 0.10P + 0.09P = 0.19P

First you have to turn your discount into a decimal. (10 % = .10) Then you multiply $650.00 x .10 = ____ . Then when you get the answer you subtract it by $650.00. After that You will get your answer.
