Misha and Dontavious were asked to solve the following problem using linear programming.

A local school district can operate a large bus for $300 per day and a small bus for $200 per day. The district needs to arrange transportation for at least 360 students for a field trip and has enough chaperones to have one chaperone per bus for up to 7 buses. Each large bus can hold 60 students and each small bus can hold 45 students. What is the minimum cost for the transportation for the field trip?

Misha decided the following represented this situation:

Let x = number of large buses

Let y = number of small buses

Objective Fx: LaTeX: C=300x+45yC = 300 x + 45 y

Constraints:

LaTeX: 200+60y\ge360200 + 60 y ≥ 360

LaTeX: x+y\le7x + y ≤ 7

LaTeX: x\ge0x ≥ 0

LaTeX: y\ge0y ≥ 0

Dontavious decided the following represented this situation:

Let x = number of large buses

Let y = number of small buses

Objective Fx: LaTeX: C=300x+200yC = 300 x + 200 y

Constraints:

LaTeX: 60x+45y\ge36060 x + 45 y ≥ 360

LaTeX: x+y\le7x + y ≤ 7

LaTeX: x\ge0x ≥ 0

LaTeX: y\ge0y ≥ 0

Decide which student set up the correct Objective function and Constraints and using that information answer the following:

a) What are the vertices for the feasible region?

b) What is the minimum cost for transportation for the field trip and how did you arrive at this cost?

Someone answer this asap rn for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =

Ialready asked this but i never got an answer. will give a high rating and perhaps brainliest. choose the linear inequality that describes the graph. the gray area represents the shaded region. y ≤ –4x – 2 y > –4x – 2 y ≥ –4x – 2 y < 4x – 2
