Answer:
y = ½x
_____
k = ½
Step-by-step explanation:
[# of donuts] 2 → [total price] $1
[# of donuts] 12 → [total price] $6
[# of donuts] 3 → [total price] $1.50
[# of donuts] 7 → [total price] $3.50
Because price is the dependent variable, it is the y value. And since the price is the y variable, the donuts must be the x value.
Because the price is ½ the # of donuts, y is ½ x which means y = ½x and k = ½.
