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

First thing to remember is that they were currently in week 0, when they began saving:The equation for Alex would look like: y=20x + 125 
See that we are on week 0, and x is our weeks, and the equation would look like: y=20(0) + 125 
Simplifying the equation, it will give us which it is 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

Answer 2

Answer: Alex starts with (E) 125 and April starts with (I) 100.

Step-by-step explanation:

Given : April and Alex are saving money to buy new phones.

Alex wrote an equation to show the total, y, she has saved at the end of each week, x.  

$y=20x+125$

To find the starting amount of Alex, put x=0 we get

$y=125$

Thus, Alex starting amount was 125.

Since April made the graph in with at x=0, y=100, thus the starting amount of April's saving is 100.

Hence Alex's starting amount is greater than April.
