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)

Question

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

Answer 1

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:

\( y = 0.40x \)
