Answer:
Step-by-step explanation:
1) y = 50x + 2500
2) y = 200x + 1000
if we build a system with the two equations, we have:
50x+2500 = 200x + 1000
150x = 1500
x = 10
y = 2000 + 1000 = 3000
3) 10
4) $3000
4th choice
Volume of cylinder: 2(pi)r^2+2pi(r)h
3x+y=5 & 5x-4y=-3
3x+5x=8x+y-4y=-3
8x+y-4y=-3
8x+3y=-3
-3 -3
8x=-6
