Question

A backpack is on sale for 25% off after the discount is taken a 7% sales tax is apply if original price of the backpack is P which equation represents the final cost C in dollars of the backpack

Answer 1

Answer:

c = p(0.75)(1.07)

Step-by-step explanation:

The original price of the backpack = p

Discount = 25%

Percentage paid = 100% - 25% = 75%

Discounted price = 75% of p

Discounted price = 75/100 x p

Discounted price = 0.75p

Sales tax = 7% of 0.75p

Final cost = 107% of 0.75p

Final cost = (107/100) x 0.75p

Final cost = (1.07)(0.75)(p)

c = p(0.75)(1.07)
