Answer 1

To determine the equation representing the relationship between the cost of the cookies (y) and the number of cookies bought (x) during the sale, we first need to find the new price per cookie after the discount.

The original price for 4 cookies is $2.00, which means the price per cookie is: \[ \text{Original price per cookie} = \frac{2.00}{4} = 0.50 \text{ dollars per cookie} \]

During the sale, the price per cookie decreases by $0.10: \[ \text{Sale price per cookie} = 0.50 - 0.10 = 0.40 \text{ dollars per cookie} \]

Now, we can write the equation that represents the total cost (y) of x cookies at the sale price: \[ y = 0.40x \]

Thus, the correct equation is: \[ \text{y} = 0.40 \text{x} \]

The correct response from your options is: y=0.40x
