Answer:
the best i can do is give you an equation
Step-by-step explanation:
y=0.05x+50 for plan A
y-0.15+5 for plan B. You didnt give much to work off or really ask a question
Well since we're dealing with the co-efficient of x, then we just have to talk about 18x^3 and divide it by 6x^2 and we get 3x. so the co-eff. is 3 so (A)
<span>if they already have 200 then the "must collect" 800 to reach 1000</span>
<span>A) 2x + 2y = -3
B) 2x -y = 5
B) y = 2x -5
Substituting equation B into A
</span><span>A) 2x +2*(2x-5) = -3
2x + 4x -10 = -3
6x = 7
x = 1.16666666
y = 2*</span><span>1.16666667 -5
y = </span><span><span><span>-2.66666666
