Answer 1

Answer:

0.5x+20=0.25x+30, m=40

Step-by-step explanation:

Blue: y=0.5x+20

Red: y=0.25+30

We’re looking for where the y (cost) is equal, so we can set the two equations to each other:

Isolate x:

0.5x+20=0.25x+30

0.5x+20-20=0.25x+30-20

0.5x=0.25x+10

0.5x-0.25x=0.25x+10-0.25x

0.25x=10

x=40

m= 40
