Answer:
11 pounds of deluxe, 35 pounds of regular
Step-by-step explanation:
If d is pounds of deluxe coffee, r is pounds of regular coffee, and C is the total cost, then:
d ≥ 11
d + r ≥ 46
C = 7d + 5r
Since deluxe costs more than regular, we want to use as little as possible to minimize the cost.
d = 11
r = 35
C = 252
Answer:
The price of an adult ticket is $9 and the price of a student ticket is $6
Step-by-step explanation:
Create a system of equations where x is the price of an adult ticket and y is the price of a student ticket:
2x + 7y = 60
3x + 11y = 93
Solve by elimination by multiplying the top equation by 3 and the bottom equation by -2, to cancel out the x terms:
6x + 21y = 180
-6x - 22y = -186
Add them together:
-y = -6
y = 6
Then, plug in 6 as y into one of the equations to solve for x:
2x + 7y = 60
2x + 7(6) = 60
2x + 42 = 60
2x = 18
x = 9
So, the price of an adult ticket is $9 and the price of a student ticket is $6
These are the same line when you graph. So there are infinite solutions to this system.
A={2,3,5}
B={1,3,4}
A∩B={3}
R: a. {3}
