Answer:Walnuts cost $1.25 and chocolate chips cost $3.25
Step-by-step explanation: Make walnuts x and chocolate chips y.
3x+5y=20
6x+2y=14
Multiply the first equation by 2 and then subtract it from the second.
-(6x+10y=40)
6x+2y=14
-8y=-26
y=3.25
Plug y back into either equation and isolate x to solve for x.
6x+2(3.25)=14
6x+6.5=14
6x=7.5
x=1.25
Answer:
They are both correct because there is more than one way to write a multivariable polynomial in standard form. Marcus has the exponents on the x variable in descending order from the highest degree to the lowest degree. Ariel has the exponents on the y variable in descending order from the highest degree to the lowest degree.
