Question

Chase goes out to lunch. The bill, before tax and tip, was $11.90. A sales tax of 9% was added on. Chase tipped 17% 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.

Answer 1

$15.17

Explanation:

First we calculate the value for the sales tax:

`11.90 * (9)/(100 ) = 1.07`

we then add the value for the sales tax ($1.07) to the initial bill:

`11.90 + 1.07 = 12.97`

We were instructed to calculate the tip after the sales tax was added so:

`12.97 * (17)/(100) = 2.20`

after we will add the value for the tip to the value that we have for the bill ( this is the new value that includes the sales tax) to find the total cost:

`12.97+ 2.20 = 15.17`

Therefore the total cost for his mean is $15.17

Answer 2

Chase's meal cost $11.90. After adding 9% sales tax and a 17% tip, the total rounded cost was approximately $15.18.

To calculate the total cost of the meal, including tax and tip, follow these steps:

1. Calculate Sales Tax:

Multiply the bill amount by the sales tax rate to find the sales tax.

`\[ \text{Sales Tax} = \text{Bill Amount} * \left(\frac{\text{Sales Tax Rate}}{100}\right) \]`

`\[ \text{Sales Tax} = $11.90 * \left((9)/(100)\right) \]`

`\[ \text{Sales Tax} \approx $1.071 \]`

2. Calculate Subtotal:

Add the bill amount and the sales tax to find the subtotal.

`\[ \text{Subtotal} = \text{Bill Amount} + \text{Sales Tax} \]`

`\[ \text{Subtotal} = $11.90 + $1.071 \]`

`\[ \text{Subtotal} \approx $12.971 \]`

3. Calculate Tip:

Calculate the tip on the subtotal.

`\[ \text{Tip} = \text{Subtotal} * \left(\frac{\text{Tip Rate}}{100}\right) \]`

`\[ \text{Tip} = $12.971 * \left((17)/(100)\right) \]`

`\[ \text{Tip} \approx $2.204 \]`

4. Calculate Total Cost:

Add the subtotal, tip, and sales tax to get the total cost.

`\[ \text{Total Cost} = \text{Subtotal} + \text{Tip} \]`

`\[ \text{Total Cost} = $12.971 + $2.204 \]`

`\[ \text{Total Cost} \approx $15.175 \]`

Therefore, the total cost of the meal, rounded to the nearest cent, is approximately $15.18.
