Question

What is a 15% tip on a meal that costs $25.00

Answer 1

$25.00/ 10= 2.50 \\ 2.50*1.5= 3.75 \\ 25.00+3.75= 28.75$
As you've got 15%, the best thing to do is to find 10%, then multiply it by 1.5. Once you've found the tip, you add this onto the cost of the meal.
Therefore, the total cost of $25 meal with a 15% tip is $28.75
Hope this helps :)
