At the deli counter in the supermarket, Nigel paid 10 for 2 1/2 pounds of roast beef

Answer 1

To find the cost per pound of roast beef, we need to divide the total cost by the weight.

Nigel paid $10 for 2 1/2 pounds of roast beef, which can also be written as 2.5 pounds.

Therefore, the cost per pound of roast beef is $10 / 2.5 pounds = $4 per pound.
