Step-by-step explanation:
Rudra should have collected the students equally both from football and pump basketball
Just solve the equations:
<span>A) X - Y = 11
B) 2x + Y = 19
Multiply A) by -2
</span>
<span>A) -2X +2Y = -22 then add to B)
</span><span>B) 2x + Y = 19
3Y = -3
Y=-1
</span>
<span>A) X - -1 = 11
x = 10
</span>
1220*24 = 29,280 per year
multiply that by number of years until he retires:
761280 / 29280 = 26 years
292800 / 29280 = 10 years
the other 2 arent even years so it should be one of those 2. I would say the larger number
