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!
Answer:
2=124 124/2
4=248 248/4
5=310 310/5
8=496 496/8
Step-by-step explanation:
40 + 22 = 62
62 x 2 = 124
62 x 4 = 248
62 x 5 = 310
62 x 8 = 496
i think
A 5% raise means that you have to find out what 5% of 8 is and then add that to 8:
5/100 * 8 = 40/100 = $0.40
8 + 0.40 = $8.40.
C is correct because both are the same numbers but they are different by significant figures.

<span>x-y=1 (1)
x+y=3 (2)
Add (1) and (2) to eliminate y:
x- y + x - y =1 + 3
2x = 4
x = 4/2
</span><span>x = 2
Substitute x = 2 into (1) to find y:
2 + y = 3
y = 3 - 2
y = 1
The solution is (2, 1) </span>
