To estimate the total cost of a haircut at the barbershop including sales tax and a 20% tip, follow these steps:
-
Calculate the sales tax on the haircut:
- Sales tax = 6% of $28
- Sales tax = 0.06 × 28 = $1.68
-
Calculate the total cost including sales tax:
- Total cost = Haircut price + Sales tax
- Total cost = $28 + $1.68 = $29.68
-
Calculate the tip:
- Tip = 20% of the haircut price
- Tip = 0.20 × 28 = $5.60
-
Calculate the total cost including the tip:
- Total with tip = Total cost + Tip
- Total with tip = $29.68 + $5.60 = $35.28
Now rounding to the nearest reasonable estimate from the given options, the closest estimate is $35.62.
Therefore, the best response is: $35.62.
