Step-by-step explanation:

Answer 2

Answer:  Phyllis starts with $50 and Chen starts with $15.

Step-by-step explanation:

Given: Phyllis and Chen are saving money to go to a football game.

Phyllis made a graph to show the total she has saved at the end of each week.

From the given graph , we can see that the y intercept of the graph =(50,0)

i.e Phyllis has $50 when he started saving.

Also, Chen wrote an equation to show the total, y, he has saved at the end of each week, x.

$y = 15x + 15$

At x= 0, we get $y=15$

Therefore, Chen has $15 when he started saving.
