Question: Danielle wants to make her own popsicles. She finds out she needs popsicle sticks, molds, and juice. She has $10 for supplies. She buys one set of molds for $3 and a pack of 100 popsicle sticks for $1. Each bottle of juice makes 20 popsicles and costs $2. How many popsicle sticks will she be left with if she makes as many as she can?
Answer: Step-by-step reasoning process: She has $6 left after buying initial supplies because 10 - 3 - 1 = 6. She can buy 3 bottles of juice because 6 / 2 = 3. She can make 60 popsicles because 20 x 3 = 60. She has 40 sticks left because 100 - 6 60 = 40.
So the answer is 40.

Question: Isabelle’s parents bought a new television for $480. The seller gives them a 5% discount. They pay a first installment of $150 and will pay the rest in 3 monthly installments. What is the amount of a monthly payment?
Answer: Step-by-step reasoning process: The television discount is $480 x 5 / 100 = $24. So, the television price is $480 - $24 = $456. The outstanding balance is $456 – $150 = $306. The monthly payment is $306 / 3 = $102.
So the answer is 102.

Question: A road has four lanes, and in each lane, the number of cars is twice as many as the number of trucks in all the lanes. If there are 60 trucks in each lane, calculate the total number of vehicles in all the lanes?
Answer: Step-by-step reasoning process: If the road has four lanes and 60 trucks in each lane, the total number of trucks in all the lanes is 60 * 4 = 240. Since in each lane the number of cars is twice as many as the number of trucks in all the lanes, there are 2 * 240 = 480 cars in each lane. The total number of cars in all the lanes is 480 * 4 = 1920. In all the lanes, the total number of vehicles is 240 trucks + 1920 cars = 2160.
So the answer is 2160.

Question: The school band is having a car wash to raise money. Their goal is to collect $150. So far they have earned $10 each from three families and $5 each from 15 families. How much more money do they have to earn to reach their goal?
Answer:
Step-by-step reasoning process: The school band earned $10 / family * 3 families = $30 from three families. The school band earned $15 / family * 5 families = $75 from 15 families. The school band earned $30 + $75 = $105 total. The school band needs $150 - $105 = $45 more to reach their goal.
So the answer is 45.
