Answer: C. 160 min
It depends what the owns they have you were. She spent a total of $120.40
N+2 and n+4.n+4 given that their sum is 81
Based on my eyesight, it looks like C intercepts the y-axis at y = 2.
Since the y-intercept is the deciding factor, let's take 2 · 4⁰
Now, 4⁰ = 1, since anything raised to the power of 0 gives 1.
Now, the intercept is at 2 · 1 = 2.
Hence, (C) is the correct graph.
