5. A Major League Baseball stadium sells three types of tickets. Reserved tickets are sold for $20 each, field-level tickets are
Ad libitum [116K]

Answer: A) When all three ticket prices generate the same revenue.

Step-by-step explanation:

Reserved tickets cost $20 each.

Field-level tickets cost $50 each.

Seat tickets cost $100 each.

Then if x represents the number of reserved tickets sold, the total revenue for the reserved tickets will be:

R(x) = x*$20

If w represents the number of field-level tickets sold, the total revenue for field-level tickets will be:

F(w) = w*$50

If y represents the number of seat tickets sold, then the total revenue for the seat tickets will be:

S(y) = y*$100

Those equations will intersect when:

R(x) = F(w) = S(y)

This will mean that they will intersect when all three tickets have the same revenue, then the correct option is:

A) When all three ticket prices generate the same revenue.

Using this diagram, select the pair of lines that must be parallel.
Bas_tet [7]

Answer:

The answer would be D: d || f.

Step-by-step explanation:

  1. Since the angles 4 and 7 are parallel, it would make sense for the lines that the angles are on to be parallel as well.
  2. It just so happens that line d and line f are completely parallel to each other and angles 4 and 7 are on the lines. So the answer would be D.
