Answer:
x = 16.5
Step-by-step explanation:
2x + 3y = 73.50
5x + 2y = 109.50
(2x + 3y = 73.5) -5
(5x + 2y = 109.5) 2
-10x - 15y = -367.5
10x + 4y =219
-11y = -148.5
y = 13.5
2x + 3(13.5) = 73.50
2x + 40.5 = 73.5
2x = 73.5 - 40.5
2x = 33
x = 16.5
Answer: 0.4%
Step-by-step explanation:
Total number of people 9000, divide the number of allergic reactions 36 by 9000.
36/9000=0.004
Now multiply 0.004 x 100 to reveal percent allergic reaction
0.004 x 100 = 0.4%
0.4% had allergic reactions
5675/25 = 227
227 bags is your answer
