Answer:
Because the number would be multiplied by an even number, which is 2. If the number (odd or even) is multiplied by two, then the result would be an <em>even number</em>.
Proof:
2(1) = 2
2(6) = 12
2(7) = 14
2(3) = 6
The number would then be added by an odd number, which is 1. If an even number is added with an odd number, then the result would be an odd number.
Proof:
2 + 1 = 3
12 + 1 = 13
14 + 1 = 15
6 + 1 = 7

Answer to the first question
Hello!
We can write an expression to show this scenario. Write this in the equation format y = mx + b:
m = rate of change, or cost per ride
b = initial cost, or cost to enter the fair
y = 2.50x + 4
Solve for the amount of rides possible with $21.50:
21.50 = 2.50x + 4
Subtract 4 from both sides to isolate x:
17.50 = 2.50x
Divide both sides by 2.50:
17.50/2.50 = 7 rides.
Not enough info. There is no way to solve for a variable with only other variables.
