Answer:
$0.30 + $0.03n > $0.02 + $0.02n
Step-by-step explanation:
company x = $0.30 + $0.03n
company y = $0.02 + $0.02n
$0.30 + $0.03n > $0.02 + $0.02n
Subtract the second equation from double the first equation:
2x+6y-2x-(-4y)=0
10y=0
Therefore, y=0. Substituting this into the first equation, we see that:
x+3(0)=3
x=3
Therefore, x=3. The solution to this system is x=3, y=0, or (3, 0).
