To find the cost, Mr. Imani has to multiply the price of the paper, $1.25, by the number of packs he wants to buy, 10, and multiply the price of the notebooks, $2.50, by the number of notebooks he wants to buy, 30. Then, he has to add the two results together:

Cost = (1.25 * 10) + (2.50 * 30)
Cost = $12.50 + $75.00
Cost = $87.50

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