Final answer:
Dezi's total cost for dinner, including a 6% tax and an 18% tip on a $52.92 bill, is approximately $65.63.
Step-by-step explanation:
We are working with a problem where Dezi buys dinner and needs to calculate the total cost including tax and tip. The original bill is $52.92, tax is at 6%, and the tip is estimated at 18%. To find the total amount Dezi will pay, we first calculate the sales tax, then the tip, and finally add these to the original bill amount to find the total cost.
Sales Tax Calculation:
To calculate the sales tax, convert the tax rate from a percentage to a decimal by dividing by 100. So, 6% becomes 0.06. Multiply this decimal by the original bill amount:
0.06 × $52.92 = $3.18
Tip Calculation:
To calculate the tip, similarly convert the tip percentage to a decimal:
0.18 × $52.92 = $9.53
Total Cost Calculation:
Add the original bill amount to both the sales tax and the tip to find the total cost:
$52.92 + $3.18 + $9.53 = $65.63
Therefore, the closest estimate of what Dezi will pay altogether for the dinner is $65.63.
