Answer:
Maximize C =


and x ≥ 0, y ≥ 0
Plot the lines on graph




So, boundary points of feasible region are (0,1.7) , (2.125,0) and (0,0)
Substitute the points in Maximize C
At (0,1.7)
Maximize C =
Maximize C =
At (2.125,0)
Maximize C =
Maximize C =
At (0,0)
Maximize C =
Maximize C =
So, Maximum value is attained at (2.125,0)
So, the optimal value of x is 2.125
The optimal value of y is 0
The maximum value of the objective function is 19.125
We are given the following equation:

Subtract both sides by 17

Take the positive/negative square root of both sides

This should be your answer. Let me know if you have any questions, thanks!
The two cities are actually 427.5 miles apart.
Standard form essentially means to not have any symbols such as "x","÷", or "power".
The equation would be written as:
(64 x 10) ^4
Then
(640) ^ 4
