It is given that four different prizes were awarded. So,
a). 4 ways for person 47 to win a prize

98 ways to give the 3rd prize
97 ways to give the last prize
∴ P(99,3) = 99 x 98 x 97
b). 1 way to give person 47 their prize
1 way to give person 19 their prize
98 ways to give out the 3rd prize
97 ways to give out the last prize

Answer:
y = 40 x = 80
Step-by-step explanation:
520 = 3.25x + 6.5y x+y=120
x+y=120
x = 120-y
520 = 3.25(120-y)+6.5y
520 = 390-3.25y+6.5y
520 = 390+3.25y
130=3.25y
Divide each side by 3.25
40 = y
x = 120-y
x = 120-(40)
x = 80
