Question

PLEASE HELP

The wholesale cost of a new sofa is $330. The price of the sofa is marked up 20% before putting it on the showroom floor. During a showroom sale, the sofa was marked down 20%.

What is the price of the sofa now? Round your answer to the nearest dollar, if necessary.

Answer 1

Answer: $317

Step-by-step explanation

Increasing by 20% means we involve the multiplier 1.20

Think of it like 100% + 20% = 1 + 0.20 = 1.20

So we go from 330 to 330*1.20 = 396 dollars.

Then we'll have a 20% discount. If you save 20%, then you pay the remaining 80%; therefore we have the multiplier 0.80

0.80*396 = 316.80 is the final price before rounding to the nearest dollar.

Here's how we write everything on one line: 330*1.20*0.80 = 316.80

Round 316.80 to the nearest dollar to get $317 as the final answer
