The number of pencils and total cost are in a proportional relationship because the cost increases with the number of pencils.

Option D is correct.

Step-by-step explanation:

The cost of One Pencil = $3

The cost of 3 Pencils = $9

So, as the number of pencils are increasing, the total cost of pencils is also increasing because cost of 1 pencil is $3 and cost of 3 pencils increases to $9

So, we can say that the number of pencils and total cost are in a proportional relationship because the cost increases with the number of pencils.

Option D is correct.

.002 is 1/10 of what
8_murik_8 [283]
This uses the concept of proportions.

.002 converted to a fraction is 2/1000, or 1/500.

We set up the proportion like so:
 10/100 = .002/x 
Solve for x.

Cross-multiply.
10 * x = .002 * 100
10 * x = .2
x = .2 / 10
x = .02

The answer is .02
