Aclub decides to sell t-shirts for $12 as a fundraiser. it costs $20 plus $8 per t-shirt to make the t-shirts. write and solve an equation to find how many t-shirts the club needs to sell in order to make a profit of at least $100.

30

Step-by-step explanation:

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

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5
