Question

Marty is at the clothing store and sees that the shirt he wants is 15% off. He knows he can use the expression c - 0.15c, where c is the cost of the shirt, to find the discounted cost of the shirt before tax. Determine if the expression below is equivalent to c - 0.15c..

Answer 1

Kindly check explanation

Explanation:

The equation for the discounted cost :

c - 0.15c

Initial cost = c

Discount percent = 15% = 15/100 = 0.15

Discount on sale = 0.15 * c = 0.15c

Hence,

Discounted price = initial price - discount on sale

Discounted price = c - 0.15c

c - 0.15c = 0.85c
