A Correct answer
Explanation

Profit = 50, which is 10% of cost. So, cost of 46 packets = 500. Cost per packet = 500/46. Cost of 56 packets = (500/46) * 56 = 608.69, which is approximately 609.

AI explanation

The problem states the profit of \$50 is 10% of the total cost price for the 46 packets, so the total cost price is 50 divided by 0.10, which is \$500. Using the unitary method, the cost price of 56 packets is found by multiplying the cost per packet of 500/46 by 56. This calculation gives 28000 divided by 46, which results in an approximate cost price of $609 for 56 packets.
