Given:

Jaime bought a notebook and a box of pencils for $5.00. The notebook cost $3.00 and there are 10 pencils in a box. The equation 3+10p=5 can be used to find the cost of one pencil.

To find:

Select all equations that are equivalent.

Solution:

We have been given the equation 3 +10p = 5 to find cost of one pencil.

In this 3 is the cost of notebook and 10p is the cost of pencil in which p is the cost of one pencil.

To solve this, we will take constants to right side

So, 3 + 10p = 5

10p = 5 -3

10p = 2, which is equivalent to option B.

Now, we will take 10p to right side and put it in division to 2.

10p = 2

p = 2/10

p = 0.20, which is equivalent to option D.

Hence, correct options are B and D.
