6.50 + 1.50 = 8

8 × .20 = 1.6

8 × .7 = .56

8 + 1.6 + .56 = $10.16

The total cost is $10.16.

Hope this helps!

The total cost is $ 10.16

Given that:

  • The cost of the lunch = $6.5
  • The cost of beverage = $1.5
  • Tip's percentage of cost of lunch = 20%
  • Sales tax on cost of lunch = 7%

To find: Total cost.

Calculations:

Total Cost = Cost of Lunch + Beverage + Tip's Amount + Sales Tax.

Cost of lunch + Beverage = 6.5 + 1.5 = $ 8

Tip's amount can be calculated as:

[tex]\begin{aligned} \:\rm Tip &= \dfrac{8 \times 20}{100}\\&= \dfrac{8}{5}\\&= \$ 1.6\end{aligned}[/tex]

Sales Tax's amount can be calculated as:

[tex]\begin{aligned} \:\rm Sales Tax &= \dfrac{8 \times 7}{100}\\&= \dfrac{56}{100}\\&= \$ 0.56 \end{aligned}[/tex]

Thus, total cost = $8 + $1.6 + $0.56 =  $ 10.16

Thus, the total cost is $ 10.16
