X - the score he must get
He must get at least 92 points.
Let x = the other rational number.
x(66/7) = (48/5)
Solve for x to find your answer.
The expected value is $38.46.
The probability of drawing a 10 from any suit is 4/52. Multiply this by the earnings, 500:
4/52(500) = 2000/52 = 38.46
First, factor out 5:
5 (x² -x -20)
We need two numbers that add to -1 and multiply to -20. -5 and 4 satisfy this.
5(x-5)(x+4)
