If you brush your teeth 10 minutes a day about how many hours do you brush in a year

61 Hours

Step-by-step explanation: There are 365 days in a year, so you brush your teeth 3,650 minutes per year (365 days times 10 minutes aka 365×10=3650). Now convert those minutes to hours by dividing it by 60 since there are 60 minutes per hour. 3,650/60 = 60.83333333333 aka 61 hours (as the question said "about how many hours, it wants you to round)

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
