Answer:1. $14.702. $1.603. $135.304. $8.25Step-by-step explanation:1. Convert percentage to decimal:30% = 30/100 = 0.3So 30% of $49 = 0.3 x 49 = 14.7Therefore, a discount of 30% = a discount of $14.702. Convert percentage to decimal:20% = 20/100 = 0.2So 20% of $8 = 0.2 x 8 = 1.6Therefore, the 20% tip = $1.603. Convert percentage to decimal:20% = 20/100 = 0.2So 20% of $112.75 = 0.2 x 112.75 = 22.55Therefore, total cost with the tip = 112.75 + 22.55 = $135.34. If a discount of 45% is applied, the new cost of the shirt will be 55% of its original price (as 100% - 45% = 55%)Convert percentage to decimal:55% = 55/100 = 0.55So 55% of $15 = 0.55 x 15 = 8.25...
