Question

Miss lmain Wants to purchase paper and notebook for a classroom. At dollar discount, he can buy packs of paper P for 1.25 each, and notebook, and for 2.50 each. This is a model by 1.25P plus 2.50 and evaluate for P = 10 and n = 30 to find how much it will cost Mr. Lmain to purchase 10 Packs of paper 30 notebooks.

Answer 1

To calculate the cost of purchasing 10 packs of paper and 30 notebooks, we need to use the given model: 1.25P + 2.50

First, let's substitute P = 10 into the equation:
1.25 * 10 + 2.50

Multiply:
12.50 + 2.50

Add:
15

So, the cost of purchasing 10 packs of paper is $15.

Next, let's substitute P = 30 into the equation:
1.25 * 30 + 2.50

Multiply:
37.50 + 2.50

Add:
40

So, the cost of purchasing 30 notebooks is $40.

To find the total cost of purchasing 10 packs of paper and 30 notebooks, we need to add the costs of each separately.

Total cost = Cost of 10 packs of paper + Cost of 30 notebooks
Total cost = $15 + $40
Total cost = $55

Therefore, it will cost Mr. Lmain $55 to purchase 10 packs of paper and 30 notebooks.

Answer 2

To find out how much it will cost Mr. Lmain to purchase 10 packs of paper and 30 notebooks, we can use the given model:

Cost = (1.25 * P) + (2.50 * n)

Where P represents the number of packs of paper and n represents the number of notebooks.

Given P = 10 and n = 30, we can substitute these values into the formula:

Cost = (1.25 * 10) + (2.50 * 30)

Let's calculate it step-by-step:

Step 1: Calculate the cost of packs of paper (1.25 * 10):
Cost of packs of paper = 12.5

Step 2: Calculate the cost of notebooks (2.50 * 30):
Cost of notebooks = 75

Step 3: Add the costs of packs of paper and notebooks:
Cost = 12.5 + 75
Cost = 87.5

Therefore, Mr. Lmain will need to spend $87.50 to purchase 10 packs of paper and 30 notebooks.

Answer 3

To find out how much it will cost Mr. Lmain to purchase 10 packs of paper and 30 notebooks, we need to substitute the given values into the expression 1.25P + 2.50.

Given: P = 10 (packs of paper) and n = 30 (notebooks)

Substituting the values into the expression:
1.25(10) + 2.50(30)

Simplifying the expression:
12.50 + 75

Adding the terms:
12.50 + 75 = 87.50

Therefore, it will cost Mr. Lmain $87.50 to purchase 10 packs of paper and 30 notebooks.
