Question

If 200 vitamins cost $4.75, what should 500 vitamins cost?

Answer 1

500 vitamins costs `$10`

Explanation:

We know that 200 vitamins cost $4.75; we are trying to find what 500 vitamins cost

In order to do this, we have to find the cost of 1 vitamin:

total cost/total amount = `($4.75)/(200)` = `$0.02` per vitamin

Now to get the cost of 500 vitamins:

`$0.02 * 500` vitamins = `$10`
