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.  How long does it take her to do a haircut?
3x + 2y = 315
2x + 4y = 450

• 45 minutes

• 90 minutes
  2x + 4y = 315

• 60 minutes
  3x + 4y = 450

• 30 minutes

Yesterday a chef used 68 eggs to make 8 chocolate souffles and 10 lemon meringue pies. The day before, he made 7 chocolate souffles and 10 lemon meringue pies, which used 62 eggs. How many eggs, does each dessert require? If (x) represents chocolate souffles and (y) represents lemon meringue pies, give the correct system of equations and the solution as an ordered pair.

• 8x + 10y = 68

  7x + 10y = 62

  ( 2, 6 )

• 8x + 10y = 68

  7x + 10y = 62

  ( 6, 2 )

• 7x + 10y = 68

  8x + 10y = 62

  ( 5, 4 )

• 7x + 10y = 68

  8x + 10y = 62

  ( 5, 3 )
