Question 1182776: Hello, I need help with my summer assignment. It's a two-part question. The first part says, "parallel to goes through (5,4)". I tried looking it up and I was able to plug the 4 in for y, and the five in for x which gave me goes through (12,2)". I also tried to look this up and I got something about reciprocal so, so far I have but I know this isn't correct so I need help with these. Thank you
Again, the two-part problem is below:
"parallel to goes through (5,4)"
"perpendicular to goes through (12,2)"

Question 1184530: A landscaping supply company produces decorative stones. A ton of coarse stones requires 2 hours ofcrushing, 5 hours of sifting, and 8 hours of drying. A ton of fine stones requires 6 hours of crushing, 3hours of sifting, and 2 hours of drying. The coarse stones sell for$400 per ton. The fine stones sell for$500per ton. In a work week, the plant is capable of 36 hours of crushing, 30 hours of sifting, and 40 hours ofdrying. Based on the demand forecast, the quantity of coarse stones produced should be at least twice thequantity of fine stones produced.
First
1. Formulate an optimization model to decide how much of each kind of stones to produce to maximizetotal revenue.
2. Solve your model using the Excel solver.
3. Using a two-dimensional plot, solve your model graphically.
Then, by modifying your two-dimensional plot, answer the following questions:
4. How much would it be worth to get another hour of crushing time?
5. How much would it be worth to get another hour of sifting time?
6. Could you find the range of the prices for the fine stones such that in the optimal solution, the quantity of coarse stones produced is exactly twice the quantity of fine stones produced.
