Question

caleb goes out to lunch. the bill, before tax and tip, was $15. a sales tax of 9% was added on. caleb tipped 14% on the amount after the sales tax was added. what was the total cost of the meal, plus tax and tip? round to the nearest cent.

Explanation:

Step1: Calculate sales tax amount

$\text{Tax} = 15 \times 0.09 = 1.35$

Step2: Find total after tax

$\text{After-tax total} = 15 + 1.35 = 16.35$

Step3: Calculate tip amount

$\text{Tip} = 16.35 \times 0.14 = 2.289$

Step4: Find final total cost

$\text{Total cost} = 16.35 + 2.289 = 18.639$

Step5: Round to nearest cent

$\text{Rounded total} = 18.64$

Answer:

$\$18.64$
