A farmer can plant up to 6 acres of land with soybeans and corn. Her use of a necessary pesticide is limited by federal regulations to 15 gallons for her entire 6 acres. Soybeans require 2 gallons of pesticide for every acre planted and corn requires 3 gallons per acre. The profit the farmer makes by earning $4,000 for every acre of soybeans he plants and $3,000 for every acre he plants with corn can be modeled by P=4000x+3000y . What is the maximum profit that she can earn?
$15,000
$21,000
$18,000
$25,000
Their is no solution region therefore there is no maximum profit.
Which of the following represents the situation:
David is running a concession stand at a soccer game. He sells nachos and sodas. Nachos cost $1.50 each and sodas cost $0.50 each. At the end of the game, David made a total of $78.50 and sold a total of 87 nachos and sodas combined. Which system of equations represents this situation?
1.5x+0.5y=78.5
x+y=87
1.5x+0.5y=78.5
1.5x+0.5y=87
x+y=78.5
1.5x+0.5y=87
x+y=78.5
x+y=87
This is a systems of inequalities so none of the equations are correct.
Which of the following represents the situation:
Carlos works at a movie theater selling tickets. The theater has 300 seats and charges $7.50 for adults and $5.50 for children. The theater expects to make at least $2000 for each showing.
x+y≤300
7.5x+5.5y≥2000
x+y<300
7.5x+5.5y≥2000
x+y≤300
7.5x+5.5y≤2000
x+y>2000
7.5x+5.5y≤300
This is a systems of equations so none of the inequalities are correct.
What is the solution to the systems
x+y=5
x-y=3

Elber bought 11 binders and notebooks from the store and spent $45. Binders cost $6 each and notebooks cost $2.50 each. Which equations would you use to find the numbers of binders, b, and notebooks, n, she purchased
b+n=11
b+n=45
6b+2.5n=11
6b+2.5n=45
2.5b+6n=11
Which graph represents the solution to the inequality
x - 4y ≤ -12
The lines on the graph should be dotted so none of the graphs are the correct solution

A
B
C
D
None of the points are in the solution region.
Which of the following is the graph for the systems of inequalities:
y ≤ -2x + 5
y > 3x - 1
The shaded region should be on the top, so none of the graphs are shaded correctly
