Question

You order two drinks for $2.49 each and an entrée for $12.95. If sales tax is 5%, what is your total bill?

Answer 1

1.05(2(2.49) + 12.95) =
1.05(4.98 + 12.95) =
1.05(17.93) =
18.8265 rounds to 18.83 <===

Answer 2

You ordered 2 drinks:

2 x 2.49 = 4.98

You ordered an entree: 12.95

Add the two numbers together

12.95 + 4.98 = 17.93

There is a 5% (or 0.05) sales tax

17.93 x 0.05 = 0.8965 (0.90 rounded)

Add the two together

17.9 + 0.90 = 18.80

$18.80 is your answer

hope this helps
