Jana needs to rent a moving van for one day. Reliable Rentals charges $20 dollars for the day and $0.50 for each mile. Dependable Rentals chargers $10 for the day and $0.80 for each mile. Jana wrote and solve the equation below to find the number of miles for which the costs of renting from the companies will be about the same. She used m to represent the number if miles. 20-0.5m=10+0.8m
20=10+1.3m
10=1.3m
m= 10/1.3 = 100/13 = 7 9/13
the cost will be equal of the van is driven about 8 miles.
