Given : Cost of Popcorn = $4.25
Given : Cost of Soda = $2.25
Total Cost of Popcorn and Soda = $4.25 + $2.25 = $6.50
Given : Sales tax on Total Bill = 5%
We need to find 5% of $6.50, in order to have the amount of Sales tax
⇒ 5% of $6.50 = [tex]\frac{5}{100} \times 6.50 = 0.05 \times 6.50 = 0.325[/tex]
⇒ Total Bill = Cost of both Popcorn and Soda + Sales tax on the both
⇒ Total Bill = $6.50 + $0.325 = $6.825
