Answer:
At 100 miles.
Step-by-step explanation:
You would probably need a graphing calculator to make it easy, or you could do trial and error, but it would take longer. You need to write an equation for both companies. Sam's equation would be 50+.25x. Greater City moving company's would be 35+.40x. You could put both equations into the calculator or try trial and error. Eventually, when x=100 miles, they both end up the same price, $75.
