Answer:

Kindly check explanation

Step-by-step 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
