Olenka [21]

The price of a senior citizen ticket  is $8 and the price of a student ticket is$ 10

Step-by-step explanation:

Let the cost of one  seniors citizen ticket be x and  student  be y

First day:

10 seniors citizen tickets and 11 student for a total of $190.

10x + 11y = 190-----------------------------(1)

Second day:

$160 on the second day by selling 5 senior citizen tickets and 12 student tickets.

5x + 12y = 160---------------------------------(2)

Multiply eq(2) by 2

10x + 24y = 320----------------------------(3)

Subtract eq(1) from (3)

10x + 24y = 320

10x + 11y = 190

-----------------------------

0x + 13 y =  130

---------------------------

13y = 130

y = \frac{130}{13}

y = 10-------------------------------(4)

Substituting (4) in (2)

5x +  12(10) =  160

5x + 120 = 160

5x = 160-120

5x = 40

x = \frac{40}{5}

x = 8

(y-(-3))=-3(x-4)

y+3= -3x+12

y=-3x+12-3
