Answer:
19 days
Step-by-step explanation:
The first day he saves 2.25.
The second day he has saved 2.25 + 2.25 or 2.25(2).
The third day he has saved 2.25 + 2.25 + 2.25 or 2.25(3)
This continues for x number of days so 2.25x.
If the video game costs 41.95 then set equal to 2.25x and solve.
2.25x = 41.95
x = 18.64
This rounds to 19.

Step-by-step explanation:
9 = a7 + b
-2 = a9 + b
b = 9-7a and b = - 2-9a
9 - 7a = - 2-9a
2a = - 11
a = - 5.5
b = 9 - 5.5*7 = - 29.5
y = -5.5x - 29.5
