Miss lmain Wants to purchase paper and notebook for a classroom. At dollar discount, he can buy packs of paper P for 125 each, and notebook, and for 250 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.
To find out how much it will cost Mr. Lmain to purchase 10 packs of paper and 30 notebooks, we first need to substitute the values of P and n in the given model.
The model states that the cost of buying paper is 1.25P and the cost of buying a notebook is 2.50.
So, the cost of buying 10 packs of paper can be calculated as:
10 * 1.25P = 10 * 1.25 * 10 = $125
And the cost of buying 30 notebooks can be calculated as:
30 * 2.50 = $75
Therefore, the total cost of buying 10 packs of paper and 30 notebooks will be:
$125 + $75 = $200
Therefore, it will cost Mr. Lmain $200 to purchase 10 packs of paper and 30 notebooks.
To find the cost of purchasing the items, we need to substitute the given values of P (10) and n (30) into the given model equation: 1.25P + 2.50.
For 10 packs of paper, we have P = 10. Substituting this into the equation:
Cost of paper = 1.25 * 10 + 2.50
Cost of paper = 12.50 + 2.50
Cost of paper = 15 dollars
For 30 notebooks, we have n = 30. Substituting this into the equation:
Cost of notebooks = 2.50 * 30
Cost of notebooks = 75 dollars
To find the total cost of purchasing 10 packs of paper and 30 notebooks, we add the costs of paper and notebooks together:
Total cost = Cost of paper + Cost of notebooks
Total cost = 15 + 75
Total cost = 90 dollars
Therefore, it will cost Mr. Lmain 90 dollars to purchase 10 packs of paper and 30 notebooks.
To find out how much it will cost Mr. Lmain to purchase 10 packs of paper and 30 notebooks, we can use the given expression:
Cost = 1.25P + 2.50
Here, P represents the number of packs of paper, and n represents the number of notebooks.
Given that P = 10 and n = 30, we can substitute these values into the expression:
Cost = 1.25(10) + 2.50 * 30
To simplify the expression, we perform the multiplication and addition:
Cost = 12.50 + 75.00
Cost = 87.50
Therefore, it will cost Mr. Lmain $87.50 to purchase 10 packs of paper and 30 notebooks.
