X = number of tickets sold in advance, and thus cheaper.
x + 206 = number of tickets sold at the door.
now, the ones sold at the door, are more expensive and is more than the early sold tickets, as you know is x + 206.
now, if the early ones cost each one 6 bucks, then the cost for all of them is 6*x, or 6x.
the ones sold at the door are 10 bucks each, and therefore their total cost is 10(x + 206).
now, we know sales in total for both was 6828, therefore,

and surely you'd know what that is.
how many were sold at the door? well, x + 206.
Graph the inequalities to find the vertices of the shaded region: (2, 3) and (8, 0).
Now, evaluate the the function C = x + 3y at those vertices to find the minimum value.
C = x + 3y at (2, 3) ⇒ C = (2) + 3(3) ⇒ C = 2 + 9 ⇒ C = 11
C = x + 3y at (8, 0) ⇒ C = (8) + 3(0) ⇒ C = 8 + 0 ⇒ C = 8
The minimum value occurs at (8, 0) with a minimum of C = 8
Answer: A
So first, you need to separate the expression and numbers. For me, i would prefer putting the expressuon on the left hand side and numbers on the right hand side. this will make the solving more clearer and easier to solve.
10p+5=18p-62
10p-18p=-62-5
-8p =-67
p= 8.375
the answer should be
p= 8.375. but however it is not in the option.
3/6 is bigger because it simplifies to 1/2 and 3/8 is below 1/2.
You can find the value of y when you substitute the x value into the equation.
Since x = 3, the equation becomes:
y = 3 + 5
The answer to question 13 is y = 8
