Based on the phrases you provided, we can set up an equation to represent the total cost of purchasing shirts.
The phrase "$9.50 for EACH shirt" suggests that if \( x \) is the number of shirts bought, then the cost for the shirts alone would be \( 9.50x \).
The phrase "PLUS a one time fee of $22.50" indicates that in addition to the cost of the shirts, there is an extra charge of $22.50.
Therefore, the total cost \( y \) can be represented by the equation:
\[ y = 9.50x + 22.50 \]
This means that the correct equation is:
\( y = 9.50x + 22.50 \)
So the correct option is:
Ay = 9.50x + 22.50
