Answer to Problem 28STP

The original price of shirt is $19.69 . The correct answer is option D

Explanation of Solution

Given information:

Cost price of the shirt is $15.75

Percentage off in shirt is 20% or 20100

The given options are,

A. $16.69

B. $17.69

C. $18.69

D. $19.69

Calculation:

The original price of the shirt is calculated as,

Firstly, the original price of shirt is taken as 'x'

Costprice = original price − ( the percentage off × original price )

  15.75=x−(20100×x)⇒15.75=x−0.2x⇒15.75=0.8x⇒x=15.750.8⇒x=19.69

Therefore, the original price of shirt is $19.69 .
