Answer:
D) y= 3.75x
Explanation:
The total cost is y, therefore you set the equation equal to y since you want to find the total cost of candy he purchased.
X is the number of pounds, and the candy is $3.75 each pound.
When you set up the equation, it is
y=3.75x
Which also means: the total cost of the candy depends on how many pounds (which is $3.75 per pound) he buys.
