Answer:To calculate the total cost including tax, we can follow these steps: 1. Determine the cost of each item before tax: - The cost of one hamburger is $6.99. - The cost of one shake is $5.79. 2. Calculate the total cost of the hamburgers: - Since you are buying 2 hamburgers, multiply the cost of one hamburger ($6.99) by 2. - The total cost of the hamburgers is $6.99 x 2 = $13.98. 3. Calculate the total cost of the shakes: - Since you are buying 3 shakes, multiply the cost of one shake ($5.79) by 3. - The total cost of the shakes is $5.79 x 3 = $17.37. 4. Add the total cost of the hamburgers and shakes: - The total cost of the hamburgers is $13.98. - The total cost of the shakes is $17.37. - The sum of these two amounts is $13.98 + $17.37 = $31.35. 5. Calculate the tax amount: - The sales tax rate in New York is 8.75%. - Multiply the total cost ($31.35) by 8.75% (or 0.0875) to find the tax amount. - The tax amount is $31.35 x 0.0875 = $2.74. 6. Calculate the total cost including tax: - Add the tax amount ($2.74) to the total cost before tax ($31.35). - The total cost including tax is $31.35 + $2.74 = $34.09. Therefore, the total cost including tax for buying 2 hamburgers and 3 shakes at the restaurant would be $34.09.
