Answer:
D. $7943.25
Step-by-step explanation:
1) because an isosceles triangle has two equal sides
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

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!
