Answer 1

To find out how much it will cost Mr. Imani to purchase 10 packs of paper and 30 notebooks, we need to substitute p = 10 and n = 30 into the model given: 1.25p + 2.50n.

Let's calculate it:

1.25p = 1.25 * 10 = $12.50
2.50n = 2.50 * 30 = $75.00

Now let's add the two amounts together:

$12.50 (cost of paper) + $75.00 (cost of notebooks) = $87.50

So it will cost Mr. Imani $87.50 to purchase 10 packs of paper and 30 notebooks.

Therefore, the correct answer is:

$87.50
