the function c(x)=18x-10 represents the cost in dollars. How many tickets can you buy?

Note: It seems you may have unintentionally missed writing the complete question. As total cost is missing.

So, I am assuming how many tickets Mr. XYZ can buy if he/she pays 188 dollars.

The solution would still clear your concept though.

Answer:

Please check the explanation.

Step-by-step explanation:

Given the function

[tex]c(x)=18x-10[/tex]

The slope-intercept form of the line equation

We know that the slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept

so

comparing with the slope-intercept form of the line equation

here:

  • rate of change = 18
  • c(x) or y represents the cost

and

'x' represents the number of tickets

Assuming the total cost i.e. c(x) = $188

In order to determine the value of x, set c(x) = 188

i.e.

188 = 18x -10

switch sides

188x - 10 = 170

add 10 to both sides

18x - 10 + 10 = 188 + 10

18x = 198

Divide 18 to both sides

18x/18 = 198/18

x =  11

Therefore, if you can buy x = 11 tickets if you pay  170 dollars.
