Answer 1

Given that 8 lbs of apples cost $17.20, the cost per pound is $2.15. Therefore, one can purchase 20 lbs of apples for $43.

Step-by-step explanation:

The question is asking how many pounds of apples can be purchased for $43, given that the cost of apples varies directly with the number of apples bought and that 8 lb of apples cost $17.20. To solve this, we use the concept of direct variation or proportional reasoning. Since 8 lbs cost $17.20, we can find the cost per pound by dividing the total cost by the number of pounds:

$17.20 ÷ 8 lb = $2.15 per lb

Now, with the cost per pound, we can calculate how many pounds of apples can be bought with $43:

$43 ÷ $2.15 per lb = 20 lbs

Therefore, one can purchase 20 pounds of apples for $43.

Answer 2

20 lbs

Step-by-step explanation:

divide 17.20 by 8 to get $2.15 per pound

divide 43 by 2.15 to get 20 lbs at 2.15 a pound.
