Question

Determine which situation could be represented by the system of linear equations given below.

Answer 1

Correct Answer: Option 4

Let x represent the number of packs of 5 paintbrushes and y represent the number of packs of 3 paintbrushes.

According to the statement, total of 60 packs were bought. So we can write the equation for this as:

$x+y=60$

Total number of paintbrushes are 210. So, each of the x packs has 5 paintbrushes and y packs has 3 paintbrushes. So we can write the equation as:

$5x+3y=210$

Therefore, option 4 is the correct answer.

Answer 2

Answer:

An art teacher bought paintbrushes in packs of 5 and packs of 3. She bought a total of 60 backs and now has 210 paintbrushes.
