Answer:
Dawn paid $7.09.
Explanation:
Dawn Lingua bought cloth to make curtains = 3 yards
Cost of the cloth = $2.25 per yard
Cost of 3 yard cloth = $2.25 × 3 = $6.75
Sales tax was = 5%
Sales tax on the total cost = 5% of 6.75
= (5/100) × 6.75 = 0.05 × 6.75 = $0.3375
Now we add sales tax to the total cost
= 6.75 + 0.3375 = $7.0875 rounded to $7.09
Dawn paid for the cloth with sales tax was $7.09
