Answer:
D (I think?)
Step-by-step explanation:
It's neither a nor b because neither of them would work if you plug in o for x.
The reason I think it's D and not C is because it goes up by 10,000 x (1.1)^x
Just not sure because because of how the question was asked. Hope this helps
4x+7y=4.88 -> mult by -3 -> -12x-21y=-14.64
12x+8y=7.88
-12x-21y=-14.64
Add the two above equations together, the y will be left:
-13y=-6.76
y=0.52 —> cost of each apple (plug back into one of original equations, I chose 4x+7y=4.88:
4x+7(0.52)=4.88
Solve for x.
x=0.31 —> cost of each orange
