Veggiburgers are $3.25 each. You order 2.
Veggiburgers total price is $6.50
Salads are $2.50 each. You order 1.
Salad total price is $2.50
Steak Fries are $1.50 each. You order 1.
Steak Fries total price is $1.50
Coffees are $0.90 each. You order 2.
Coffees total price is $1.80
Add up all of the prices for the total price.
$6.50 + $2.50 + $1.50 + $1.80 = $12.30
Your cost is $12.30 without taxes or tips
1% of $12.30 is $0.123
Multiply $0.123 by 4 to get 4%.
That is $0.492
Now round to get rid of the 0.002
Your taxes are $0.49
Your question does not have enough information. We need to know if you tip on the taxes, because some people tip before taxes and others tip after taxes.
In order to fully answer you then, we can get two answers, one with the tip on taxes and one without.
Tipping on taxes:
Add the taxes to the total to get $12.79 and then get %10 by moving the decimal over once. 10% of $12.79 is $1.279
Divide $1.279 by 2 to get 5%, which is $0.6395
Add together $1.279 + $0.6395 (that is 15% together..) + $12.79 = $14.7085
$14.7085 rounds up to get rid of the $0.0085, rounding to $14.71
The answer, with tip based on tax, is $14.71
Not tipping on taxes:
We already know 1% of $12.30 to be $0.123, so we multiply that by 15 to get 15%, which is $1.845
Then we add the unrounded tax, the tip, and the total cost together.
$0.492 + $1.845 + $12.30 = $14.637
Now we round up to get rid of the $0.007, so the answer, with tip not based on tax, is $14.64
