Several students have a really great business plan and decide to start a graphic t-shirt company. after initial expenses of $280, they will purchase each t-shirt wholesale for $3.99. they will then sell the each shirt for $10.99. how many must they sell to break even?
a.
25 shirts
b.
70 shirts
c.
40 shirts
d.
18 shirts

Option c.

Step-by-step explanation:

Fixed cost = $280

Variable cost = $3.99 per T-shirt.

Revenue = $10.99 per T-shirt.

Let the number of T-shirts be x.

Total cost = Fixed cost + Variable cost

Total cost = 280+3.99x

Total revenue = 10.99x

Formula for profit:

Profit = Revenue - Cost

Profit = 10.99x - (280+3.99x)

Profit = 10.99x - 280 - 3.99x

Profit = 7x - 280

For break even, the value profit is 0.

0 = 7x - 280

280 = 7x

Divide both sides by 7.

They must sell 40 T-shirts to break even.

Therefore, the correct option is c.
