A clothing store used the sign show below to advertise a discount on shirts:

Murljashka [212]

Tax= Tax %(Price of 2 Shirts + 50% of 3rd Shirt)
Tax= 7.1%[49.96+49.96+1/2(49.96)]
Tax= 0.071(49.96+49.96+24.98)
Tax= 0.071(124.90)
Tax= $8.8679

Total= Tax + Price of Shirts
Total= $8.8679 + $124.90
Total= $133.7689 or rounded $133.77

Mean Price= Total ÷ 3
Mean= $44.5893 or rounded $44.59

Answer: C) $44.59
