Answer 1

To find the total cost for Mr. Imani to purchase 10 packs of paper and 30 notebooks, we need to substitute $p=10$ and $n=30$ into the cost equation $1.25p+2.50n$:

$$1.25(10)+2.50(30)$$

Calculating each term:

• For the packs of paper: $$1.25\times 10=12.50$$

• For the notebooks: $$2.50\times 30=75.00$$

Now, add the two amounts together:

$$12.50+75.00=87.50$$

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