A grocery store sells bananas, where 6 bananas cost $3. How much will 14 bananas cost at this rate? Use the scale factor to help you solve.
First, calculate the cost per banana by dividing the total cost by the number of bananas:
$3 / 6 bananas = $0.50 per banana
Next, use the cost per banana to find the cost of 14 bananas:
$0.50 per banana x 14 bananas = $7
Therefore, 14 bananas will cost $7 at this rate.
