Step-by-step explanation:
We find the equation of the solid blue line:
The line decreases by 1 unit for every 3 units across.
=> Slope of line = -1/3.
Also the y-intercept is 1.
=> Line equation: y = -1/3 x + 1.
We see that the graph below this line is shaded.
Therefore all y-values below or on the line are represented by the graph.
=> y <= -1/3 x + 1.
The answer is y <= -1/3 x + 1.
She would have saved 30 dollars.
Basically you are multiplying each thing by 5
1 stage 1
5 stage 2
25 stage 3
125 stage 4
625 stage 5
3125 stage 6
