Question
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=0.50x−0.10
y equals 0.50 x minus 0.10
y=0.40x
y equals 0.40x
y=0.50x
y equals 0.50x
y=0.60x

To determine the equation that represents the relationship between the cost of the cookies \( y \) and the number of cookies \( x \) during the sale, we need to calculate the price per cookie during the sale.
Originally, the baker charges $2.00 for 4 cookies. Therefore, the price per cookie is:
\[
\text{Price per cookie} = \frac{2.00}{4} = 0.50
\]
During the sale, the baker charges $0.10 less for each cookie:
\[
\text{Sale price per cookie} = 0.50 - 0.10 = 0.40
\]
The relationship between the total cost \( y \) and the number of cookies \( x \) is given by:
\[
y = 0.40x
\]
Thus, the correct equation is:
\[
y = 0.40x
\]
So, the appropriate response is:
**y=0.40x**
