We have a question: Calen originally had 5 more pencils than does Caleb, and Caleb has 3 less than twice as many pencils as does Candy. If Calen lost 10 pencils, which left him with 10 pencils, then how many pencils does Candy have?
And an answer: 9
So how you got the answer?
If Calen lost 10 pencils, which left him with 10 pencils, then Calen originally had 10 + 10 = 20 pencils. Calen originally had 5 more pencils than does Caleb, and thus Caleb has 20 - 5 = 15 pencils. Let's let "x" represent the number of pencils owned by Candy. Since Caleb has 3 less than twice as many pencils as does Candy, then (2 * x) - 3 = 15. This simplifies to 2 * x = 18. Thus, the number of pencils owned by Candy is x = 9 pencils.

We have a question: Libby has 160 quarters in her piggy bank. She has to pay $35 to replace her sister's dress that she borrowed and ruined. After replacing the dress, how many quarters will Libby have left?
And an answer: 20
So how you got the answer?
There are 4 quarters in every dollar, so $35 x 4 = 140 quarters. Libby has 160 quarters 140 quarters to repay her sister = 20 quarters left.

We have a question: Kylie picks apples for 3 hours. The first hour she picks 66 apples. The second hour she doubles her apple picking rate, and the third hour she picks a third of the apples picked in the first hour. How many apples did Kylie pick total?
And an answer: 220
So how you got the answer?
First hour = 66 apples. Second hour = 66(2) = 132 apples. Third hour = 66(1 / 3) = 22 apples. Total number of apples picked 66 + 132 + 22 = 220 apples.
