Cheyanne is saving for a car. The amount she has saved for the car, f(x), can be represented by the function f(x) = 65x + 750, where x is the number of weeks she has saved. Suppose 750 changed to 700. Which of the following is the meaning of this in the context of the problem?

AChanging 750 to 700 means the initial amount she saved decreased.
BChanging 750 to 700 means the initial amount she saved increased.
CChanging 750 to 700 means the amount she saves each week decreased.
DChanging 750 to 700 means the amount she saves each week increased.

Verified Answer :

The function f(x) = 65 x + 750 can be explained as:
slope(rate of change) = 65 
Initial value (y-intercept) = 750
So,
Using the above information we can conclude that :
A. Changing 750 to 700 means the initial amount she saved decreased.
