Question 366926: I have a word problem for inequalities and domain. Dani can rent a van for either $80.00 with unlimited mileage or $45 with 100 free miles and an extra charge of .40 cents for each mile over 100. For what number of miles traveled would the unlimited mileage plan save Dani money?

---------------------
1st Plan: A(x) = 80
2nd Plan: B(x) = 45 + 0.40(x-100)
----
Solve: A(x) < B(x)
80 < 45 + 0.4(x-100)
35 < 0.4x- 40
0.4x > 75
x > 187.5 miles
