1- Julie got a 25% discount in total. Which means she only paid 3/4 of the original price, so we have the equation:
3x/4 = 306, where x is the original cost. We need to leave the x alone, so we do:
x = 306 * 4 / 3. And by solving that we get 408. That's what the flute originally costed.

2- Here we only have to leave the x alone just like the last time:
y(x-1) = z
x-1 = z/y
x = (z/y) + 1

3- The three angles in the inside of a triangle add up 180, so we form an equation, clear the x and solve:
15 + 85 + x = 180
x = 180 - 15 - 85
x = 80

4- Let x and y be as follows:
x: Sarah's age.
y: Her brother's age

The info we have lets us form two equations:
x = 2y (Because she's twice as old)
x = y+15 (Because the difference between them is 15)

Now we only need to form and equation with both x formulas and solve it:
2y = y + 15
2y - y = 15
y = 15. So her brother is 15 years old.

5- 1 liter = 1000 milliliters

6- The cost of \$5 is for vehicle and driver. So an extra of \$1.50 was charged. Taking in count that 50 cents are charged per person:
150 / 50 = 3. So three extra people were there. We don't have to forget the driver, so 4 people were in the vehicle.

7- The first equation lets us know the value of x:
3x + 5x = -8
8x = -8
x = -8 / 8
x = -1
So x + 1 is equal to 0.

8- We only have to clear it a bit and leave a zero alone:
x^2 + 2x = 24
x^2 + 2x - 24 = 0
Now we use factorization and get:
(x+6)(x-4) = 0
We form two equations (one for each factor) where we clear the x and get two solutions:
x+6 = 0. So x = -6 is a solution.
x-4 = 0. So x = 4 is another solution.
As the second equation we formed is equal to the first one, Both -6 and 4 are solutions of x^2 + 2x = 24.

9- There's a 1 out of 6 probability of getting a 5, that's aproximately 16.7%

10- By 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105 and 210 itself.
