Question

Company S Per Shirt Shipping

Cool Shirts $8.00 $13.00
Total Tees $7.50 $16.00
How many shirts
must be
purchased so that
the cost is the
same at both
companies?

Answer 1

The number of shirts to be purchased for price to be same is 6 .

Explanation:

Given as :

The price for cool shirt = $ 8

The shipping charge for cool shirt = $ 13

The price for Tees = $ 7.50

The shipping charge for Tees = $ 16

Now, Let The number of shirts = S

So , According to question

∵ price to be same for both companies

∴ $ 8 × S + $ 13 = $ 7.50 × S + $ 16

Or, $ 8 × S - $ 7.50 × S = $ 16 - $ 13

Or, 0.5 S = 3

∴ S =
`(3)/(0.5)`

I.e S = 6

Hence The number of shirts to be purchased for price to be same is 6 . Answer
