Answer:
A system of equations that represents the situation is:
3x + 2y = 315..... Equation 1
2x + 4y = 450...... Equation 2
Step-by-step explanation:
Let the number of
Haircuts = x
Hair dyes = y
Hence:
Alexandra finds that she can give:
3 haircuts and 2 hair dyes in 315 minutes.
3x + 2y = 315..... Equation 1
Giving 2 haircuts and 4 hair dyes takes 450 minutes
2x + 4y = 450...... Equation 2
Therefore:
a system of equations that represents the situation is:
3x + 2y = 315..... Equation 1
2x + 4y = 450...... Equation 2
