What you should do for this case is write a weighted average to represent the problem.
We have then:
Average = (((tickets1) * (class1)) + ((tickets2) * (class2)) + ((tickets2) * (class3))) / ((class1) + (class1) + (class1))
answer:
an expression for the average number of tickets sold per school child is
Average = (((tickets1) * (class1)) + ((tickets2) * (class2)) + ((tickets2) * (class3))) / ((class1) + (class1) + (class1))
Answer:

Step-by-step explanation:
285 × (1 + 75/100)^n
285 × (1.75)^n
1994 is 9 years later
285 × (1.75)⁹
43,871.986370085
Answer:
the answer is A. 1
Step-by-step explanation:
y2-y1/x2-x1=
3-(-3)/11-5=
6/6=
1
3r + 36 = -9 - 2r
5r = -45
r = -9
I double checked it works.
