Hello there!
First we want to do $25 times 10%.
10% as a decimal is 0.10.
We then do 25 * 0.10 and we get $2.50
$2.50 is what the waiter would get as a tip.
We then want to add $25 times 8%
8% as a decimal is 0.08.
We then do 25 * 0.08 and we get $2.00
$25.00 (Bill) + $2.00 (Tax) + $2.50 (Tip) = $29.50.
Therefore, the total amount of cash you should pay with should be that, or $30.00 if you round up.
Hope this helped, have a great day!
