If Dana continues to drink 500 ml of soda each day, how long will the 2-liter bottle of soda last? There are 1,000 ml in 1 liter. How many ml are in a 2-liter bottle of soda? ** There are 2*1,000 ml = <<2*1000=2000>>2,000 ml in a 2-liter bottle of soda. How many days will the 2-liter bottle of soda last? ** A 2-liter bottle of soda lasts 2,000/500 = <<2000/500=4>>4 days. #### 4 If Beth is 18 years old and her little sister is 5, in how many years would she be twice her sister's age? How many years is the age difference between Beth and her sister? ** The age difference between Beth and her sister is 18 - 5 = <<18-5=13>>13 years. How old would Beth be if she were twice her sister's age? ** Beth must be 13 x 2 = <<13*2=26>>26 to be twice her sister's age. How many years will it be until Beth is twice her sister's age? ** Beth will be twice her sister's age in 26 - 18 = <<26-18=8>>8 years. #### 8 At a birthday party, there are 20 red balloons and 15 green balloons. Before the party started, 3 red and 2 green balloons burst. How many balloons are left? How many balloons are there? ** There are a total of 20 + 15 = <<20+15=35>>35 balloons at the party.
