George runs an outlet where he sells personalized T-shirts. He spends $35 to rent the printing machine and $25 for phone service each month. If each T-shirt costs $5.80, and he sells them for $10, George will start making a profit after selling shirts in a month.

15 shirts

Step-by-step explanation:

Cost of rent = $35

Cost of printing + phone service = $25

Cost price of 1 T-shirt = $5.80

Selling price = $10

Profit = ?

To determine the profit, we'll first of all determine the cost he use to run the shop and find the value from his profit on each shirt.

Cost of start up monthly = cost of rent + cost of machine = $35 + $25 = $60

Cost price of each shirt = $5.80

Selling price on each shirt = $10

Profit on each shirt = $10 - $5.80 = $4.20

For him to break even, he must sell a certain number of shirts

Let the number of shirt be x

$60 = $4.2x

X = 14.29

Rounding it the nearest whole number, x = 15 shirts.

He'll need to sell at least 15 shirts to start making profits
