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
B. 0 ÷ 28 = 0
C. 28 – 0 = 0
D. 28 ÷ 0 = 0
x + 2y = 5

Also, a frequency polygon allows for the inclusion of open-ended classes, making it more flexible in representing data with varying ranges.
