A system of equations is good for a problem like this.
Let x be the number of student tickets sold
Let y be the number of adult tickets sold
x + y = 200
2x + 3y = 490
x = 200 - y
2(200 - y) + 3y = 490
400 - 2y + 3y = 490
400 + y = 490
y = 90
The number of adult tickets sold was 90.
x + 90 = 200 --> x = 110
2x + 3(90) = 490 --> 2x + 270 = 490 --> 2x = 220 --> x = 110
The number student tickets sold was 110.

Total = Principal * (1 + rate/n)^n*years where "n" is the number of compounding periods
Total = 9,250 * (1 + .07/52)^52*5
Total = <span>9,250 * (1.0013461538</span>)^260
<span><span>Total = 9,250 * 1.418733571
</span>
</span><span>Total = 13,123.29</span>

What do you mean? i don’t quite get this question
Answer:
f(1) = 8
Step-by-step explanation:
Step 1: Define
f(x) = 7(x - 1) + 8
f(1) = x = 1
Step 2: Substitute and evaluate
f(1) = 7(1 - 1) + 8
f(1) = 7(0) + 8
f(1) = 8
