Let x be the number of t-shirts. The t-shirts are sold at $12 and it takes $20 for all the tshirts plus $8 per tshirt. The profit is defined as the price sold minus the price to make the tshirts:
We can solve for x:
The company must sell 30 tshirts to atleast make $100 profit
<span>12x = money made 20+8x = cost where x is the number of t-shirts made selling for $12 ea ... Amount made - cost = profit 12x - (20+8x) = 100 12x - 20 - 8x = 100 4x = 100 + 20
