Question 1086618
The student council's cost will be 191 + 4n, where n = the number of shirts ordered.
If they charge $11 per shirt, their revenue will be 11n
In order for them to make a profit, their revenue must be greater than their cost:
11n > 191 + 4n
7n > 191
n > 27.28
So they must sell at least 28 shirts to make a profit.
