Question

Brian has started a savings account. The balance, g(x), in his account can be represented by the function g(x) = 25x + 350, where x is the number of weeks he deposits money. Suppose 25 changed to 35. What does this mean in the context of the problem

Answer 1

The correct answer is C. Changing 25 to 35 means the amount he deposits each week increased.

Because every week he deposited $35.

Answer 2

For the answer to the question above, It means Brian is switching from saving $25 dollars a week to $35 dollars a week. Because every week Brian will add $25 to his savings account (In week 1, Brian adds $25. In week 2 Brian adds $50. And so on). So to change from 25 to 35 would mean that Brian is saving more money every week ($10 to be exact). 

And if you're curious, $350 stands for the amount of money Brian has initially (because at 0 weeks, Brian has $350 in his savings account). 

I hope this helps
