Reasoning and answer: She bought 10 - 4 = 6 adult tickets. So 6 * 30 = $180 was the cost for adult tickets. Children tickets cost 30 / 2 = $15 each. So the children tickets cost 15 * 4 = $60. So the total cost of tickets is 60 + 180 = $240. They get a 240 * .2 = $48 discount. So the tickets cost 240 - 48 = $192. So in total she paid 192 + 5 = $197.
The answer: 197

Question: Emma buys 2 containers of milk every school day for lunch. She does not go to school on the weekends. How many containers of milk does she buy in 3 weeks?

Reasoning and answer: On the second day, the company paved 4 * 2 - 1 = 7 miles. The company has 16 - 7 - 4 = 5 miles of road remaining to pave. They will need 3 * 5 = 15 truckloads of asphalt to pave 5 miles of road. For 15 truckloads, they will need 15 * 2 = 30 bags of gravel. Thus, the company will need 30 / 5 = 6 barrels of pitch to finish the road on the third day.
The answer: 6

Question:
A roadwork company is paving a newly constructed 16-mile road. They use a mixture of pitch and gravel to make the asphalt to pave the road. Each truckloads of asphalt uses two bags of gravel and five times as many bags of gravel as it does barrels of pitch to make. It takes three truckloads of asphalt to pave each mile of road. The company paved 4 miles of road on one day, then one mile less than double that on the second day. How many barrels of pitch will the company need to finish the remaining road on the third day?
