A family eats at a restaurant. The bill is $42. The family leaves a tip and spends $49.77. How much was the tip in dollars? Round your answer to the nearest hundredth (second) decimal place. Do not include units ($) in your answer

Subtract the bill from the total

so

49.77-42=$7.77

therefore

the answer is 7.77
