Answer: $32.20 for the total bill & $4.20 for a 15% tip.
Step-by-step explanation: To find a 15% tip on a $28 dinner, all you have to do is simply multiply $28 by 15%. First, convert 15% to a decimal. 15 divided by 10 = 0.15.
Next, multiply 28 x 0.15 to find the tip. 28 x 0.15 = 4.20
So a 15% tip on a $28 dinner is $4.20
To find the total of the bill add $4.20 to $28, which gives you a total bill of $32.20.
