he final cost of a sale item is determined by multiplying the price on the tag by 75%. Which best describes the function that represents the situation?

y=.75x

Step-by-step explanation:

We use percents in decimal form to multiply it with the price. We convert percents into decimals by dividing the percent number by 100. For example, 78% divided by 100 becomes 0.78.

For finding the price we pay during a sale, we focus on the percent we pay. If 25% off is the sale, then we spend 75% or 100-25=75. 75% is 0.75. Multiply that by x an unknown price and we have 0.75x.
