A family eats at a restaurant. The bill is $42. The family leaves a tip and spends $49.77. How much was the tip in dollars? [ Select ] How much was the tip as a percentage of the bill

18.5% of the bill.

Step-by-step explanation:

Since the bill was 42 dollars while the total amount was 49.77, we need to subtract 42 by 49.77.

49.77 - 42 = 7.77.

So the tip was $7.77.

But then we also have to find the tip as a percentage.

So we should do 7.77 divided by 42, because 42 is the original amount.

7.77 ÷ 42 = 0.185, but as a percent you have to move to the left two places. So the decimal is 18.5.

In conclusion, the tip was 18.5% of the bill.

Hope this helps!
