Answer:

675

Step-by-step explanation:

If the price is 20 % off, then we will pay 100-20 = 80 percent of the original price

Let x be the original price

x* 80% = 540

Change to decimal form

x * .80 = 540

Divide each side by .80

.80x / .80 = 540/.80

x =675

The original price is 675

svetoff [14.1K]

34% because to find the percentage you need to divide the amount in the time, 264, by the total amount of records, 778, and when you do that you get around .335, and convert that to a percentage you multiply it by 100, and you get 33.5%, but then you round it up to 34%.
