While on vacation in livingston, brooke went out for a dinner that cost $100. if sales tax in livingston is 11% and brooke left a 20% tip on $100, what was the total cost of her meal?

The cost of her meal is $100, we need to figure out:

To find the sales tax, we put the sales tax over the total bill, 11 / 100, since the bill is 100, 11 dollars is the sales tax.

Then Add:

100 + 11 = 111

We have 111 as our bill. We need to figure out the tip, which is 20. Put it over 100, our actual cost of the dinner, 20 / 100, since it's over 100, it's 20 dollars.

Add:

111 + 20 = 131

Therefore, the total cost of the dinner is 131 dollars.

Best of Luck to you!
