Answer 2

Answer:  The art club president need to buy 14 bottles of paint for the project.

Step-by-step explanation:  Given that each of the 14 students in the art club needs 4 ounces of paint for a project. The art store sells paint only in 8-ounce bottles.

We are to find the number of bottles of paint that the art club president need to buy for the project.

We will be using the unitary method to solve the given problem.

Number of bottles filled by 8 ounces of paint = 1.

So, the number of bottles filled by 1 ounce of paint is

$\dfrac{1}{8}.$

So, the number of bottles filled by 4 ounces of paint will be

$\dfrac{1}{8}\times4=\dfrac{1}{2}.$

Now, number of bottles of paint needed by 1 student $=\dfrac{1}{2}.$

Therefore, the number of bottles of paint needed by 14 students will be

$\dfrac{1}{2}\times14=7.$

Thus, the art club president need to buy 14 bottles of paint for the project.
