is the system of equations representing the situation.

Step-by-step explanation:

Given:

Alexandra finds that she can give 3 haircuts and 2 hair dyes in 315 minutes. Giving 2 haircuts and 4 hair dyes takes 450 minutes.

Now, to find the system of equations representing the situation.

Let the number of haircuts be $x.$

Let the number of hair dyes be $y.$

So, Alexandra can give 3 haircuts and 2 hair dyes in:

$3x+2y=315.$

Now, giving 2 haircuts and 4 hair dyes in:

$2x+4y=450.$

Therefore,

$3x+2y=315\\\\2x+4y=450$

is the system of equations representing the situation.
