Answer:
Bella bought the t-shirt at $9.54 each.
Step-by-step explanation:
We are given the following in the question:
"T-shirts at Perfect Tee cost either $9 or $10 depending on the style."
Cost of 13 t-shirts = $124
We have to find the cost of each t-shirt.
Cost of 1 t-shirt =
[tex]=\dfrac{\text{Total cost of t-shirts}}{\text{Number of t-shirts}}\\\\=\dfrac{\$124}{13}\\\\=\$9.5384\approx \$9.54[/tex]
Thus, Bella bought the t-shirt at $9.54 each.
