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 equation:

\[ 1.25p + 2.50n \]

where:

• \( p \) is the number of packs of paper,
• \( n \) is the number of notebooks.

Plugging in the values \( p = 10 \) and \( n = 30 \):

\[ 1.25(10) + 2.50(30) \]

Calculating each part:

1. \( 1.25 \times 10 = 12.50 \)
2. \( 2.50 \times 30 = 75.00 \)

Now add these two amounts together:

\[ 12.50 + 75.00 = 87.50 \]

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