Final answer:
The equation to find the cost of one candy when 10 candies cost 100 cents is '10x = 100'. By dividing both sides of the equation by 10, we find that x = 10 cents per candy.
Step-by-step explanation:
The correct equation to find the cost of a candy (x) when 10 candies cost 100 cents is:
d. 10x = 100
To solve for x, you divide both sides of the equation by 10:
x = 100 / 10
x = 10 cents per candy
This means that each candy costs 10 cents.
