Avery is deciding between two landscaping companies for her place of business.
Company A charges $45 per hour and a $300 equipment fee. Company B charges
$70 per hour and a $200 equipment fee. Let A represent the amount Company A
would charge for t hours of landscaping, and let B represent the amount Company B
would charge for f hours of landscaping. Write an equation for each situation, in
terms of t, and determine the interval of hours, t, for which Company A is cheaper
than Company B.
