A local discount store is famous for their motto, "Shop with us and you'll pay 20% less". Their claim is that every item in the store is already marked down 20% off of retail prices. In this Sunday's ad, they are advertising a scuba mask and snorkel set at their discount price of $28. Use a percent model to determine the original retail price of the scuba mask and snorkel set.

Use percentage multipliers:
$28/0.8 = $35
The original price of the set is $35.

Hope This Helps!

Answer:

Original retail price: $35

Step-by-step explanation:

20% off means that the discounted price is equivalent to 80% (100% - 20%) of the retail price.  

Calling x the retail price of the scuba mask and snorkel set, then a discounted price of $28 means that this amount of money is 80% of x. Mathematically:

80*x/100 = $28

x = $28*100/80

x = $35
