The equation system is
1.25x+0.75 (92-x)=87.5
Solve for x
1.25x+69-0.75x=87.5
0.5x+69=87.5
0.5x=87.5-69
0.5x=18.5
X=18.5÷0.5
X=37 units of candy bras
(92-37)=55 units of water bottles
Mr's Powell's class sold more items
Let's look which class earned more
Mr's Powell's class earned
55×0.75=41.25
Mr's Rodman's class earned
37×1.25=46.25
So from above
Mr's Rodman's class earned more
Hope it helps!
Well I believe it's 33.333333%
Given :
If a number is tripled , it give same result as 28 is added to.
To Find :
We need to find that number.
Solution :
Let, the number is x.
Mathematical equation of the given scenario is :
3x = x + 28
3x - x - 28 = 0
2x - 28 = 0
x = 14
Therefore, the which give such result is 14.
