Kyle's family bought 4 adult tickets and 2 student tickets for $52. Maria's family bought 3 adult tickets and 5 student tickets
Troyanec [42]
Adult tickets cost $10 each and student tickets cost $6 each.

Given:
Kyle's family bought 4 adult tickets and 2 student tickets for $52
Maria's family bought 3 adult tickets and 5 student tickets for 60.

Let us assign x as the adult tickets and y as the students tickets

Kyle's family:  4x + 2y = 52
Maria's family: 3x + 5y = 60

Let us find the value of x using Kyle's equation:
4x + 2y = 52
4x         = 52 - 2y
  x         = (52 - 2y)/4
  x         = 13 - y/2
Substitute the value of x in Maria's equation to find y.
3x + 5y = 60
3(13 - y/2) + 5y = 60
39 - 3y/2 + 5y = 60
     - 3y/2 + 5y = 60 - 39
     - 3y/2 + 5y = 21
  2(-3y/2 + 5y) = 2(21)
     -3y + 10y = 42
               7y = 42
           7y/7 = 42/7
                y = 6

x = 13 - y/2
x = 13 - 6/2
x = 13 - 3
x = 10

To check:
Kyle's Family                      Maria's Family
4x + 2y = 52                        3x + 5y = 60
4(10) + 2(6) = 52                  3(10) + 5(6) = 60
40 + 12 = 52                        30 + 30 = 60
52 = 52                                 60 = 60

DIA [1.3K]

Answer:

  350 mL

Step-by-step explanation:

Let q represent the quantity (in mL) needed of the 70% solution. Then the total amount of mixture will be q+50 milliliters. The total amount of alcohol in the mixture will be ...

  0.70q +0.30(50) = 0.65(50 +q)

  .05q = 17.5 . . . . . . subtract (0.65q +1.50)

  q = 350 . . . . . . . . . divide by 0.05

You will need 350 mL of the 70% solution.
