Question 2 options:
Use the five-step thinking plan to help you solve this problem.
Pencils sell for 18 cents each, and pens sell for 69 cents each. How much would 14 pencils and 11 pens cost?
Step 1: Identify the problem or question.
The problem is to find out how much 14 pencils and 11 pens would cost.
Step 2: Gather relevant information.
The cost of one pencil is 18 cents.
The cost of one pen is 69 cents.
We need to find the cost of 14 pencils and 11 pens.
Step 3: Formulate a plan.
To solve this problem, we will multiply the cost of one pencil by 14 to find the total cost of pencils. Then, we will multiply the cost of one pen by 11 to find the total cost of pens. Finally, we will add the total cost of pencils and pens together to find the overall cost.
Step 4: Solve the problem.
Cost of 14 pencils = 18 cents/pencil x 14 pencils = 252 cents or $2.52
Cost of 11 pens = 69 cents/pen x 11 pens = 759 cents or $7.59
Total cost = Cost of pencils + Cost of pens = $2.52 + $7.59 = $10.11
Therefore, 14 pencils and 11 pens would cost $10.11.
Step 5: Evaluate the solution.
The solution makes sense and is reasonable.
To solve this problem using the five-step thinking plan, follow the steps below:
Step 1: Identify the problem:
The problem is to determine the total cost of purchasing 14 pencils and 11 pens, given their individual prices.
Step 2: Gather necessary information:
The information provided is that pencils sell for 18 cents each and pens sell for 69 cents each, and we need to find the total cost of purchasing 14 pencils and 11 pens.
Step 3: Formulate a plan:
To find the total cost, we can multiply the price of each item by the number of items and then add the results.
Step 4: Solve the problem:
The total cost of purchasing 14 pencils would be 14 pencils * 18 cents/pencil = 252 cents.
The total cost of purchasing 11 pens would be 11 pens * 69 cents/pen = 759 cents.
Step 5: Evaluate the solution:
To find the combined cost of the pencils and pens, we add the two costs together:
252 cents + 759 cents = 1011 cents.
Therefore, the cost of purchasing 14 pencils and 11 pens would be 1011 cents.
To calculate the cost of 14 pencils and 11 pens, you need to multiply the number of each item by its respective price and then add the two totals together. Follow these steps:
Step 1: Determine the price of one pencil
Since one pencil costs 18 cents, the price of 14 pencils would be 14 multiplied by 18 cents.
14 pencils * 18 cents/pencil = ?
Step 2: Calculate the price of 14 pencils
Multiply the number of pencils (14) by the price of one pencil (18 cents).
14 * 18 cents = ?
Step 3: Determine the price of one pen
Since one pen costs 69 cents, the price of 11 pens would be 11 multiplied by 69 cents.
11 pens * 69 cents/pen = ?
Step 4: Calculate the price of 11 pens
Multiply the number of pens (11) by the price of one pen (69 cents).
11 * 69 cents = ?
Step 5: Find the total cost
Add the prices of the pencils and pens together.
Total cost = price of 14 pencils + price of 11 pens
Now perform the calculations from the previous steps to find the answer.
