You need to rent a moving truck for a day. You have identified two companies that rent trucks. Company A charges $50 per day plus $0.25 per mile. Company B charges $35 per day plus $0.30 per mile. For how many miles will the cost of renting be the same? miles
Q. You need to rent a moving truck for a day. You have identified two companies that rent trucks. Company A charges $50 per day plus $0.25 per mile. Company B charges $35 per day plus $0.30 per mile. For how many miles will the cost of renting be the same? miles
Set up equation: Let's denote the number of miles driven as ' extit{m}'. We need to set up an equation where the cost of renting from Company A is equal to the cost of renting from Company B.Company A's cost: $50+$0.25mCompany B's cost: $35+$0.30mSet the two costs equal to each other to find the number of miles where they will be the same.$50+$0.25m=$35+$0.30m
Subtract to isolate terms: Subtract $35 from both sides to isolate the terms with 'm' on one side.$50−$35+$0.25m=$35−$35+$0.30m$15+$0.25m=$0.30m
Subtract to get 'm' terms: Now subtract $0.25m from both sides to get the 'm' terms on one side and the constants on the other.$15+$0.25m−$0.25m=$0.30m−$0.25m$15=$0.05m
Divide to solve for 'm: Divide both sides by $0.05 to solve for 'm'.$15/$0.05=$0.05m/$0.05m=300
