A wireless carrier offers the following plans that a person is considering.

The Family Plan:
$70monthly fee, unlimited talk and text up to 5 devices, and data charges of $40 for each device up to 2GB of data per device.
Mobile Share Plan: $85 monthly fee for up to 10 devices , unlimited talk and text for all the lines, and data charges of
$35 for each device up to a shared total of 10GB of data.
Find the model of the total cost for both companies for one month, using P for the number of devices that need data plans as part of their cost.
Assuming they stay under their data limit, find the number of devices that would make the two plans equal in cost. ___devices
