[AI-generated answer — Bot GPT 3.5]

The cost of one shirt is $15.

Therefore, the total cost of three shirts is 3 * $15 = $<<3*15=45>>45.
The sales tax is 7% which means the tax amount is 7/100 * $45 = $3.15.
The final cost of all three shirts plus sales tax is $45 + $3.15 = $<<45+3.15=48.15>>48.15. Answer: \boxed{48.15}.
