Question

A pet supply store is having a 25% off sale. Which equation represents the sales price, P, for a purchase if n is the original price?

A. P = n + (0.25n)
B. P = n - (0.25n)
C. P = 0.25n
D. P = n - (1.25n)

Answer 1

The equation that represents the sales price, P, for a purchase if n is the original price is P = n - (0.25n), which is option B.

Step-by-step explanation:

The equation that represents the sales price, P, for a purchase if n is the original price is P = n - (0.25n), which is option B.

To calculate the sales price, we subtract 25% of the original price from the original price. This is because a 25% sale means the customer pays only 75% of the original price.

For example, if the original price is $100, the sales price would be $100 - (0.25 * $100) = $100 - $25 = $75.
