suppose you invest $1500 in equipment to put pictures on t-shirts. you buy each t-shirt for $3. after you have placed the picture on a shirt, you sell it for $20. how many t-shirts must you sell to break even?

I NEED WORK!!

To break even, you need to cover your initial investment of $1500. Let's calculate the number of t-shirts you must sell to achieve this.

First, let's determine the cost of producing each t-shirt. You buy each t-shirt for $3 and incur additional costs for placing the picture on it, which we'll assume to be negligible for simplicity.

Thus, the cost of production per t-shirt is $3.

Next, we need to determine the profit margin on each t-shirt. You sell each t-shirt for $20, so the profit per t-shirt is $20 - $3 = $17.

Now, we can calculate the number of t-shirts you need to sell to break even:

Break-even point (in dollars) = Initial investment
Break-even point (in t-shirts) = Break-even point (in dollars) / Profit per t-shirt

Break-even point (in t-shirts) = $1500 / $17

Using long division, we can calculate the number of t-shirts you must sell to break even:

88 (number of t-shirts)
----------
$170 (remainder)

Therefore, you would need to sell 88 t-shirts to break even.

89

Amber, from your earlier statement, you have trouble setting up these problems. Apparently you don't have any trouble with the actual algebraic manipulations. But I and some others have helped you with several of this type. This problem is very similar to the others you have posted. My point is that you need the practice in learning how to do these. I think you should try these on your own and see if you can work through them. I couldn't do these when I was your age but I persevered. Practice, praactice, practice. Give it a shot. Let us help you with those you can't do but tell us what you have tried and why you don't know what to do next.
