A leather costing $199.99 is placed on sale at a discount of 20%. At the end of the sale, the sale price is increased by 20%. At the next sale; the new price is again discounted by 20%. Later, the sale price was increased by 20%. What is the difference between the original price and the final price? please answer correctly (full answers)

$15.679216

Step-by-step explanation:

new sp = 80% of cp

= 0.8 x 199.99

= 159.992

new sp2 = 120% of cp2

= 1.2 x 159.992

÷ 191.9904

new sp3 = 80% of cp3

= 0.8 x 191.9904

= 153.59232

new sp4 = 120% of cp4

= 1.2 x 153.59232

= 184.310784

difference = 199.99 - 184.310784

=15.679216

the answer would be c:   ax + b = ax + c
