Bot GPT 4-o mini To find the cost of 15 pounds of grapes based on the rate of 4 pounds for $6, we'll first determine the price per pound.
- Calculate the price per pound: \[ \text{Price per pound} = \frac{\text{Total price}}{\text{Total pounds}} = \frac{6}{4} = 1.50 \]
So, each pound of grapes costs $1.50.
- Calculate the cost for 15 pounds: \[ \text{Cost for 15 pounds} = 15 \times \text{Price per pound} = 15 \times 1.50 = 22.50 \]
Therefore, 15 pounds of grapes would cost $22.50.

Determine the scale factor:
To find how many times 15 is as much as 4, we divide 15 by 4. \[ \text{Scale factor} = \frac{15}{4} = 3.75 \]
Thus, 15 pounds of grapes is 3.75 times as much as 4 pounds.
Summary:
- Cost of 15 pounds of grapes: $22.50
- Scale factor: 3.75 (15 is 3.75 times as much as 4)
