Answer: <span>B)-2x^8y^18</span>
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
Hope this helps! :)
