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 amoun

WINSTONCH [101]

Answer:

$15.17

Step-by-step explanation:

First we calculate the value for the sales tax:

$11.90 \times \frac{9}{100 } = 1.07$

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:

$12.97 \times \frac{17}{100} = 2.20$

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
