Sorry, there was an error in the previous response. You could respond there instead of a new one.
The difference is $6, and each minute costs a difference of 3 cents.
Therefore at $6/0.03=200 minutes, the two are equal. Under 200, XYZ is less expensive.

the phone company has two plans for cell phones. the first plan calls for a monthly fee of 35.00 with unlimited calling. The other plan is a monthly fee of 15.00, with a 0.50 fee for every minute over 100 used in a month. What is the greatest number of minutes that you can use in the second plan and still pay less than the first plan?
