Word problem Your long distance telephone provider offers two plans. Plan A has a monthly fee of $15 and $0.25 per minute. Plan B has a monthly fee of $20 and $0.05 per minute. Write and solve an equation to find the number of minutes that you must talk to have the same cost for each of the plans.

15+ 0.25x = 30

-15 -15

0.25x=15

x=60

So for plan a, you can talk for 1 hr for $30

20+0.05x = 30

-20 -20

0.05x=10

200x=10

Plan B you can talk for 200 mins for 30 dollars.

y=mx+b

step-by-step explanation:

m slope, b y-intercept

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
