A phone company charges a sign-up fee of $3.50, plus $x for every hour the phone is used. If Brian talked on the phone for 12 hours and paid a total of $75.50, which of the following equations can be used to find, x, the hourly rate of the phone plan?
3.50 + x = 75.50

A local gym charges $580 per year for a membership, plus $20 for a one-week boot camp class. If Jason has less than $800 per year to spend for a gym membership and boot camp classes, which inequality can be used to find c, the greatest number of boot camp classes Jason can take in one year?
580 < 20c – 800
800 ≥ 580 – 20c
580 ≤ 20c + 800
800 > 580 + 20c
