Jamia is deciding between two longdistance telephone plans:
• Plan A charges $5 per month plus 6¢/min.
• Plan B charges $20 per month plus 1¢/min.
Jamia usually makes about 200 min of long distance calls each month.
Which plan costs less? Show your calculations.

costA=6m+500
costB=m+2000
plug in m=200 and see which gives you the smaller value
