A school is planning a field trip for 250 students. Each bus can hold 45 students. The cost of a bus is $350. If the school also needs to pay $15 per student for entrance fees, describe how you would apply the 'E' and 'S' steps of the CUBES strategy to solve for the total cost of the field trip. You do not need to calculate the final answer, but explain your thought process for these two steps.

For 'E' (Evaluate and eliminate unnecessary information), I would determine that all given numbers (250 students, 45 students per bus, $350 per bus, $15 per student entrance fee) are relevant to finding the total cost, so there is no extraneous information to eliminate. For 'S' (Solve the problem and check your work), I would first calculate the number of buses needed by dividing the total students (250) by the bus capacity (45) and rounding up to the next whole number. Then, I would multiply the number of buses by the cost per bus ($350) to find the total bus cost. Next, I would multiply the total number of students (250) by the entrance fee per student ($15) to find the total entrance fee cost. Finally, I would add the total bus cost and the total entrance fee cost to get the total cost of the field trip. I would then check my calculations and ensure the answer makes sense in the context of the problem.

Key concepts

3 concepts

1
The CUBES strategy offers a systematic framework designed to break down multi-step word problems, enhancing comprehension and accuracy.
2
The first two steps of the CUBES strategy are 'C' for Circle all key numbers and 'U' to Underline the question.
3
The 'B' in CUBES signifies Boxing any math action words, 'E' requires students to Evaluate and eliminate unnecessary information, and 'S' instructs them to Solve the problem and check their work.

Part 3 of 4

Practice

3 questions

In the CUBES strategy, what is the primary purpose of the 'E' step?

Consider the following word problem: 'A baker made 325 cookies on Monday. On Tuesday, she made 150 more cookies than on Monday. If she sold 400 cookies by Wednesday, how many cookies does she have left?' Apply the 'C', 'U', and 'B' steps of the CUBES strategy to this problem. List the circled numbers, the underlined question, and the boxed math action words.

Quick comprehension check

“Apply the CUBES strategy to solve the following problem, showing each step of the strategy and your final solution: A local animal shelter is holding a fundraising event. They sold 125 tickets for $15 each. They also had a silent auction that raised $850. The shelter spent $300 on event decorations and refreshments. If their goal was to raise $2,000, and they also received a separate $250 donation from a local business, how much more money do they need to reach their fundraising goal?”
