. REAL NUMBERS AND LINEAR EQUATIONS Solving a decimal word problem using a two-step linear inequality - Rachel is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices. Company A charges $97 and allows unlimited mileage. Company B has an initial fee of $55 and charges an additional $0.70 for every mile driven. For what mileages will Company A charge less than Company B? Use m for the number of miles driven, and solve your inequality for m

Explanation / Answer

Charges for company A = 97

Charegs for company B = 55 + 0.70*m

we have to find m such that :

97 < 55 + 0.70*m

=> 0.70m > 97 - 55

=> 0.70 m > 42

=> m > 42/0.70

=> m > 60
