Which of the following contributes the LEAST to the problem of antibiotic resistance?
A. taking antibiotics for all infections, including viral infections
B. stopping taking the antibiotics as soon as you feel better, thereby decreasing the exposure of the bacteria to the antibiotics
C. using high doses of antibiotics in animal feed, so that we are not exposed to the bacteria
D. taking the entire course of antibiotics as prescribed by the doctor

First set your variables: let x be the number of adult tickets and let y be the number of student tickets. Now when you write 4x it will say how much money came from adult tickets, and 2y will do the same for students. 4x+2y= the amount of money collected. 4x+2y=360 Solve the above equation for x and y and that will give you the number of tickets sold.

4x+2y=360 x+y= 105 => 4x+4y= 4*105= 420 4x+2y =360
4y-2y = 420-360= 60 2y = 60 =>** y= * 60:2=* 30 => x= 105-30=75 Verify 4 75+2*30= 300 + 60 = 360 *

The linear system modeling the situation consists of the equations x + y = 105 and 4 x + 2 y = 360 . Solving these equations, we find that the school sold 75 adult tickets and 30 student tickets. Thus, the total tickets sold add up correctly to 105 with the revenue matching at $360.
