We define variables:
 y: total amount
 x: number of days
 The system of equations is:
 y = 20x + 15
 y = 30x + 5
 The solution to the system is the ordered pair:
 (x, y) = (1, 35)
 Answer:
 (x, y) = (1, 35)
 Graphic number 2 (from left to right)

Answer: Second graph is representing the correct situation.

Explanation:

Let x is the number of days. Then, according to the question

we get two equations y=20x+15 ------(1) and y=30x+5  ------(2)

on solving these two equations we get, x=1, y=35

Thus, (1,35) is the intersection point of the lines (1) and (2).

which is only showing in graph second.

Thus, second option is correct.
