Mariulka [41]

Step-by-step explanation:

In a standard deck of 52 cards, there are 2 red aces, 2 red Queens, and 13 spades.  That leaves 35 cards for everything else.

For the game to be fair, the cost must equal the expected value.  The expected value is the sum of each outcome times its probability.

C = (12) (13/52) + (20) (2/52) + (38) (2/52) + (0) (35/52)

C = 68/13

C ≈ 5.2308

Firlakuza [10]
The first thing you should do for this case is to find the equation of the line that best suits the problem and then plot it.
 Let
 x: number of months
 y: amount paid.
 The equation of the line is
 y = 15x + 25
 y-intercept = 25
 the slope = 15
