jenny wants to buy a winter coat for $200. the store advertises that customers can take 25% off the original price and then take
777dan777 [17]
Hello!

Let's check:

200 * 25% = 50

200 - 50 = 150

150 * 10% = 15

150 - 15 = 135

So, with the 25% and then an extra 10% off, the coat would cost $135.

200 * 35% = 70

200 - 70 = 130

So, Jenny's friend is incorrect, because that is not the same as a 35% discount.

3a - 4(5) = 6

3a  - 20 = 6
