But three shirts for $15 each tax 7% what is the total cost including tax

Answer 1

To find the total cost including tax, we need to calculate the total cost of the three shirts first, and then add the tax.

Total cost of three shirts = $15/shirt * 3 shirts = $<<15*3=45>>45

Tax amount = 7% * $45 = $<<0.07*45=3.15>>3.15

Total cost including tax = $45 + $3.15 = $<<45+3.15=48.15>>48.15
