The student council at Clarksville High School is making T-shirts to sell for a fundraiser, at a price of $10 apiece. The costs, meanwhile, are $8 per shirt, plus a setup fee of $98. Selling a certain number of shirts will allow the student council to cover their costs. What will the costs be? How many shirts must be sold?

Costs are $490

49 shirts are sold

Step-by-step explanation:

98 + 8x = 10x

98 = 2x

49 = x

98 + 8(49) = $490 in costs

49 shirts sold

This is a fair game.

To find the expected value, we need to first multiply the fraction for each event by the outcome. Then, add all of the values together.

(1/6) x 0 = (1/2) x 40 + (1/3) x (-60)

0 + 20 + (-20) = 0

Since, the outcome is neither positive or negative, it is a fair game.
