The order of magnitude is calculated by use of log function. log(240000) = 5.38 so the order is 5 (from what I've see we round down even if it was 5.999 but this may be wrong in some cases).
42.51 is the right answer
Ah, direct variation/proportion.
That is simply a linear equation with a y-intercept of 0.
So... let's solve this.
Simply put, a direct variation multiplies the x-value by a constant to get the y-value.
Let's take the point

on this graph and solve for the constant of proportionality:

We easily solve that and get our answer of

. (B)
Answer:
0
