isaac keeps track of the miles per gallon his car gets per week. he has accumulated the following data: (1, 24), (2, 24.48), (3, 24.97), (4, 25.47) what is the common difference or ratio?

The common difference is 0.48.

Step-by-step explanation:

Goes up by 0.48 every time. Arithmetic = difference

Easy to tell what it is. So I think the answer is supposed to be a.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
