Answer:
The 28 bananas weigh 7 pounds
Explanation:
We can start by figuring out the price per banana by dividing the total price by the number of bananas:
Price per banana = $3 / 7 bananas
Price per banana = $0.43 per banana (rounded to the nearest cent)
Next, we can use the price per banana to find the cost of 28 bananas:
Cost of 28 bananas = 28 bananas x $0.43 per banana
Cost of 28 bananas = $12.04
Therefore, Luke pays $12.04 for 28 bananas.
To find the weight of 28 bananas, we can use the fact that seven bananas weigh 1 3/4 pounds:
Weight of one banana = 1 3/4 pounds / 7 bananas
Weight of one banana = 1/4 pound per banana
Then we can multiply the weight of one banana by 28 to find the total weight of 28 bananas:
Weight of 28 bananas = 1/4 pound per banana x 28 bananas
Weight of 28 bananas = 7 pounds
Therefore, the 28 bananas weigh 7 pounds.
