Question

A shopper bought three of the same shirt and paid $63 after the discount. What was the orignal price of the shirts?

Answer 1

Let x = the price of one shirt

 

Since he bought 3 shirts, he will pay three times the amount.  Also, there is a discount.  With the discount, the total cost is $63.

 

We can set up an equation to represent this scenario.  Assuming we have a 30% discount as David said

 

3(x - 0.3x) = 63

 

Just so you understand, (x - 0.30x) is the sales price for one shirt.  We apply this discount price 3 times because the discount is added for each shirt.

 

 

Solve for x from this equation to get the price for one shirt.

 

3(0.70x) = 63

 

2.1x = 63

 

x = 30

 

 

The price is $30.

Answer 2

This problem had some missing information.  Looking this up, it looks like the problem had a 30% discount.

 

One nice way to start is to work out the original price

Discounted Price=Original(1-0.3)

D=R*0.7

 

Solving 

R=D *10/7=$63*10/7=90

 

Each of the shirts, then is 1/3 * $90=$30
