To find an equation to describe the relationship between t and c you:
1. Find what is the dependent variable and the independent variable
In this case the total cost of the tickets depend of the number of tickets. Then:
Dependent variable is C
Independent variable is T
-----------------------------------------------------------
You can see in the table that the difference between the cost of the tickects is 165 for every 3 tickets. you find this by substracting the data in every column, as follow:
Then, the equation will be a lineal equation with a slope of:

You use a point of the lineal relationship to find the equation:
(2,110) t1=2 c1= 110
You use the next formula:

You replace the coordinates of the point and find the value of b:


The equation is:
Answer: 78
Step-by-step explanation:
Answer:
Her heart beats 75 times per minute.
Step-by-step explanation:
Okay, for this one, I recommend setting up a proportion table. First you will figure out that her heart beats 225 times approximately in 3 minutes (no duh), and literally all you have to do is divide 225 by 3. That's all! Then you'll get 75! I hope this helped you!
Answer: <u>17</u>

Equation: 8 - (-9)
Keep Change Change (KCC): 8 + 9
8 + 9 = 17
Have a great day!
