Vera is currently using 16,000 MB of
storage on her phone, and she is deleting 2.2
MB of music each minute. Keira is currently
using 11,275 MB of storage on her phone, and
she is adding 16.7 MB of music each minute.
Write an inequality that could be used to find
the number of minutes it will take for Vera to
be using no more than the amount of storage
that Keira is using.
