Answer:
Percent of bill that was tip = 15%
Explanation:
Tip = 90 cent
Price of meal = $6.00
Converting dollar to cent
1 cent = 1/100 dollar
90 cent = 90/100 dollar = 0.9 dollar
Percent of bill that was tip = Tip/Price of meal * 100
Percent of bill that was tip= 0.9/6 * 100%
Percent of bill that was tip = 15%
