Question

Mr imani wants to purchase paper and notebooks for his classroom. At Dollar Discount he can buy packs of paper, p , for $1.25 each and notebooks, n , for $2.50 each. This is modeled by 1.25p + 2.50n . Evaluate for p = 10 and n=30 to find how much it will cost Mr. Imani to purchase 10 packs of paper and 30 notebooks.

Answer 1

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

\[ \text{Total Cost} = 1.25p + 2.50n \]

Now, we can substitute \( p = 10 \) and \( n = 30 \) into the equation:

\[ \text{Total Cost} = 1.25(10) + 2.50(30) \]

Calculating each term:

\[ 1.25(10) = 12.50 \]

\[ 2.50(30) = 75.00 \]

Now, add the two amounts together:

\[ \text{Total Cost} = 12.50 + 75.00 = 87.50 \]

Therefore, the total cost for Mr. Imani to purchase 10 packs of paper and 30 notebooks is $87.50.
