<em>Note: It seems you may have unintentionally missed writing the complete question. As total cost is missing.</em>
<em>So, I am assuming how many tickets Mr. XYZ can buy if he/she pays 98 dollars. </em>
<em>The solution would still clear your concept though.</em>
Answer:
Please check the explanation.
Step-by-step explanation:
We know that the slope-intercept form of the line equation
y = mx+b
where m is the slope and b is the y-intercept
Given the function
c(x) = 18x -10
comparing with the slope-intercept form of the line equation
- rate of change = slope = m = 18
- c(x) or y represents the cost
According to the function equation,
- 'x' represents the number of tickets
Assuming the total cost i.e. c(x) = $98
In order to determine the value of x, set c(x) = 98
i.e.
98 = 18x -10
switch sides
18x - 10 = 98
add 10 to both sides
18x - 10 + 10 = 98 + 10
18x = 108
Divide 18 to both sides
18x/18 = 108/18
x = 6
Therefore, if you can buy x = 6 if you pay 98 dollars.
