Problema Solution
You need a new cell phone for emergencies only. company A charges $12 per month plus $0.10 per minute, and Company B charges $o.15 per minute with no monthly service charge. For how many minutes will the monthly cost be the same?
Answer provided by our tutors
let 'm' represent the number of minutes
Company A charges:
0.1m + 12
Company B charges:
0.15m
we want to solve for equal monthly cost:
0.1m + 12 = 0.15m
solving for 'm' we have m=240
for 240 minutes, the monthly cost will be the same
