The dimensions of the base of Box 1 are x by 3x.
The base area of Box 1 is:
3x^2
A) 4 price reductions.
B) The maximum predicted sales revenue per customer is $30.25 which occurs with 5 price reductions.
As a matter of interest, the $30 revenue per customer also occurs with 6 price reductions but this happens after reaching the maximum predicted revenue per customer of $30.25.
468=40x+18(x-3)
468=40x+18x-54
468=58x-54
522=58x
9=x
I'm not sure if you need to know x at all, if not, the top equation is all you need.
1. To translate to the left, add to x.
The equation is: y = |x + 2|
2. To translate down, add to y.
The equation is: y + 2 = |x| OR y = |x| - 2 (subtract 2 from each side)
Hope this helps!
