70 number of t-shirt to be sold.

The total cost will be $770.

Step-by-step explanation:

The student council will sell a certain number of shirts to cover their costs.

Now, let us assume the number of t-shirts to be made is x and sold to cover the cost.

So, Total cost (C) = 140 + 9x

And, Total revenue (R) = 11x

Hence, from the conditions given, C = R

⇒ 140 + 9x = 11x

⇒ 2x = 140

⇒ x = 70

So, 70 number of t-shirt to be sold.

The total cost will be $ (140 + 9 * 70) = $770. (Answer)
