How many shirts must be purchased so that the cost is the same at both companies

To find out how many shirts must be bought so that the cost is the same at both companies, we need to set up an equation and solve for the number of shirts.

Let's assume x represents the number of shirts.

The total cost at Company A is given by: Cost_A = (per shirt cost at Company A) * x + shipping cost at Company A

Similarly, the total cost at Company B is given by: Cost_B = (per shirt cost at Company B) * x + shipping cost at Company B

In this case, we have the following equations:

Cost_A = (8 * x) + 13
Cost_B = (7.50 * x) + 16

To find the number of shirts, we need to set the two total costs equal to each other:

(8 * x) + 13 = (7.50 * x) + 16

Now, we can solve this equation to find the value of x.

Begin by subtracting (7.50 * x) from both sides:

(8 * x) - (7.50 * x) = 16 - 13

Simplifying:

0.50 * x = 3

Divide both sides by 0.50 to isolate x:

x = 3 / 0.50

x = 6

Therefore, the cost will be the same at both companies if you buy 6 shirts.
