Answer:
The tip is $7.17
Total amount spent is $43.02
Explanation:
The bill is $35.85
The tip is 20%
You want to find 20% of $35.85 so multiply 35.85 by .2 (20% to decimal is .2)
35.85 multiplied by .2 gives you $7.17
So the tip is going to be $7.17
The total amount the family pays is the sum of the tip and the bill so
tip + bill = $7.17+$35.85 = $43.02
hope this helps
