Question

April and Alex are saving money to buy new phones. Each friend starts with some money and saves a specific amount each week.

Answer 1

They where right (: i got a 80% 

Answer 2

First thing to note is that we are on week 0, when they start saving:

The equation for Alex is:

y=20x + 125 

Know that we are on week 0, and x is our weeks, that makes our equation:

y=20(0) + 125 

Which means it's really:

y=125

That means that the first one is E. 125

For the second, it shows our week 0, which is at 100.

That means that the second one is I. 100

Hope this helps!
