A baker is selling sugar cookies in his shop. He charges $2.00 for 4 cookies. He has a sale over the weekend and charges $0.10 less for each cookie. Write an equation to represent the relationship between the cost of the cookies, y, and the number of cookies bought, x, during the sale.(1 point)

Responses

y=0.60x
y equals 0.60x

y=0.50x−0.10
y equals 0.50 x minus 0.10

y=0.50x
y equals 0.50x

y=0.40x

To find the equation that represents the cost of cookies during the sale, we need to determine the price per cookie after the discount.

Initially, the baker charges $2.00 for 4 cookies, which gives a price per cookie of:

\[ \text{Price per cookie} = \frac{2.00}{4} = 0.50 \]

During the sale, he charges $0.10 less per cookie:

\[ \text{Sale price per cookie} = 0.50 - 0.10 = 0.40 \]

Now, we can relate the total cost \( y \) to the number of cookies \( x \) during the sale:

\[ y = 0.40x \]

So, the correct equation is:

\( y = 0.40x \)
