Which is bigger 40 percent of 1,000 or one quarter of 1200?

40% of a 1000 equals 40/100 multiplied by 1000. This simplifies to 4/10 multiplied by 1000, which equals 400.

One quarter of 1200 equals 1/4 multiplied by 1200, which equals 300.

So we can see that 40% of 1000 is greater then one quarter of 1200.

I hope this helped! 

4*25= 100 (total points) 
x + y = 24 4x-2y = 66
since he only answered 24 questions 
therefore max he can get is 96
x + y = 24
4x-2y = 66 from first equation,
 y = 24-x plug that in second equation :
4x - 2(24-x) = 66
4x - 48 + 2x = 66 
 6x = 114
x = 19
