Answer:
The equation to find the total cost for buying x shirts would be y = 11x + 30
Explanation:
The equation y = 11x + 30 represents the total cost of buying x jerseys, where x is the number of jerseys and y is the total cost. The $11 represents the cost of each jersey and the $30 is the one-time fee for the design. So, for every jersey purchased, the cost goes up by $11, and the $30 fee is added on top of that.
