The jewerly store is having a sale. Necklaces that were regulaey priced at $23.50 are on dale for $18.80. What is the percentage
AveGali [126]
What we need to do is find the difference between the two numbers to find the difference in price and then figure out what the percent of 23.5 that is

23.50-18.80=4.7

now we'll set up a proportion

4.7       x
----- = -----
23.5   100

then cross multiply and divide

100×4.7=470/23.5=20

the percent of decrease is 20%

I hope I've helped!
