Dawn Lingua bought three yards of cloth to make some curtains. The cloth was on sale for $2.25 per yard. Dawn paid for the cloth with sales tax was $7.09. Solution: Cost of 3 yard cloth = $2.25 × 3 = $6.75; Sales tax on the total cost = 5% of 6.75 = (5/100) × 6.75 = 0.05 × 6.75 = $0.3375; 6.75 + 0.3375 = $7.0875.
