Clare's mother gave her $47 to go to the store. Clare bought 4 loaves of bread and 2 cartons of milk. Each loaf of bread cost $2 and each carton of milk cost $2. How much money does Clare have left? Give the rationale and then the answer.
Let's think step by step. The cost of the loaves of bread is 4 × $2 = $8. The cost of the milk is 2 × $2 = $4. The total cost of the groceries is $8 + $4 = $12. Clare has $47 − $12 = $35 left.. The answer is: 35.

Three years ago, Bethany was twice the age of her younger sister. In 5 years, her younger sister will be 16. How old is Bethany now? Give the rationale and then the answer.
Let's think step by step. First find how old Bethany's sister currently is: 16 years - 5 years = 11 years. Then find how old her sister was 3 years ago: 11 years - 3 years = 8 years. Then double that age to find how old Bethany was three years ago: 8 years * 2 = 16 years. Then add 3 years to that number to find how old Bethany is now: 16 years + 3 years = 19 years.. The answer is: 19.

Sab and Dane sold 6 pairs of shoes that cost $3 each and 18 shirts that cost $2. How much will each of them earn if they divided their total earning? Give the rationale and then the answer.
Let's think step by step. They earned 6 x $3 = $18 for the shoes they sold. They earned 18 x $2 = 36 for the shirts they sold. So, they earned $18 + $36 = $54 in total for the clothing they sold. Therefore, Sab and Dane earned $54 / 2 = $27 each.. The answer is: 27.
