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
y equals 0.50x
y=0.60x
y equals 0.60x
y=0.50x−0.10
y equals 0.50 x minus 0.10
y=0.40x
, and the number of cookies bought, x
, during the sale.(1 point)

To determine the cost per cookie during the sale, we start with the original cost per cookie. The baker sells 4 cookies for $2.00, so the cost per cookie is:
\[
\frac{2.00}{4} = 0.50
\]
During the sale, each cookie costs $0.10 less, so the sale price per cookie is:
\[
0.50 - 0.10 = 0.40
\]
Thus, the equation representing the relationship between the cost of the cookies \( y \) and the number of cookies bought \( x \) during the sale is:
\[
y = 0.40x
\]
So, the correct response is:
**y = 0.40x**
\[
\frac{2.00}{4} = 0.50
\]
During the sale, each cookie costs $0.10 less, so the sale price per cookie is:
\[
0.50 - 0.10 = 0.40
\]
Thus, the equation representing the relationship between the cost of the cookies \( y \) and the number of cookies bought \( x \) during the sale is:
\[
y = 0.40x
\]
So, the correct response is:
**y = 0.40x**
