Step-by-step explanation:

The question is not complete

<em>Brenda's school is selling tickets to a spring musical. On the first day of ticket sales the school sold 3 senior citizen tickets and 9 child ... The school took in $67.00 on the second day by selling 8 senior citizen tickets and 5 child tickets. What is the price each of one senior citizen ticket and one child ticket?</em>

Given data

let senior citizens be x

and children be y

so

3x+9y= 75--------------1

on the second day

8x+5y= 67------------2

solve 1 and 2 above

3x+9y= 75     X8

8x+5y= 67      X3

 24x+72y=600

-24x+15y=201

   0x+57y= 399

divide both sides by 57

y= 399/57

y= $7

put y= 7 in eqn 1 above

3x+9*7= 75

3x+63= 75

3x=75-63

3x=12

x= 12/3

x= $4

Answer:

8.

Denote the equation : y = ax + b

Use the first 2 values of x and y in table:

3a + b = 21

5a + b = 35

Subtract the 2 equations:

=> 2a = 14 => a = 7 => b = 21 - 3 x 7 = 0

=> The solution is  y = 7x

9.

Denote the equation : y = ax + b

Use the first 2 values of x and y in table:

5a + b = 17

10a + b = 22

Subtract the 2 equations:

=> 5a = 5 => a = 1 => b = 17 - 5 x 1 = 17 - 5 = 12

=> The solution is  y = x + 12

Hope this helps!
