Several students decide to start a t shirt company. after initial expenses of $280, they purchase each t shirt wholesale for $3.99. they sell each t shirt for $10.99. how many must they sell to break even? a-10 shirts b-20 shirts c- 30 shirts d- 40 shirts

40 shirts

Step-by-step explanation:

The break-even point is that point where the cost and revenue graphs intersect.

Up front, expenditures are $280 + ($3.99)t, and this is to be set equal to revenue:  ($10.99)t:

($10.99)t = $280 + ($3.99)t.

Begin solving this by subtracting ($3.99)t from both sides of this equation.  The result is

($7/shirt)t = $280.

Dividing both sides by ($7/shirt), we get

          $280

t = = 40 shirts

      ($7/shirt)

Revenue will equal costs (expenses) when these students have sold 40 shirts.

b) well because you get well

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
