Find 8% of the price of the snack combo. Do this by setting up a proportion and cross multiplying to solve for x. This will look like:
[tex] \frac{8percent}{100percent} [/tex] = [tex] \frac{x}{2.50} [/tex]
Basically, you set it up like this because you want to find what value of x will be equal to 8% over 100%. In order to figure out what x is, you will need to cross multiply the two diagonal from each other, and then divide whatever answer you get from the 3rd number. This will be:
2.5*8 = 20
20/100 = 0.20 cents
0.20 cents is your tax. So add that to your price, $2.50, and you will have your total price.
You get: $2.70
