Margaret is certain that every time she parks in the municipal garage it costs her at least $2.20. If the garage charges 45 cents plus 25 cents for each half hour, how long is Margaret's car parked?

let 'x' represent the number of hours that Margaret's car is parked
45 + 25*(2x) >= 220 (since $2.20 = 220 cents)
by solving we find:
x >= 3.5 hr
