1. Jan spends part of her year as a member of a
gym. She then finds a better deal at another
gym, so she cancels her membership with the
first gym and spends the rest of the year with
the second gym. The membership to the first
gym costs $80 per month, while the
membership for the second gym costs $45 per
month. If she ends up spending a total of $645
over the course of the year, how much time did
she spend at each gym?
