You want to rent a moped to go cruising in Daytona Beach during spring break. If bobs bikes charges $20.90 a day plus .15 a mile while mudslingers mopeds charge $15.00 a day and .20 a mile when will north plans cost the same? For what number of miles will Bahamas bobs be cheaper?
Answer provided by our tutors
let 'x' be the miles that i will cross in 1 day.
bobs bike's will charge me: 20.90 + 0.15*x
mudslingers mopeds will charge me: 15 + 0.20*x
the both places will cost the same when
20.90 + 0.15*x = 15 + 0.20*x
0.20*x - 0.15*x = 20.90 - 15
x = 118 miles
Both places will charge the same for 118 miles.
For what number of miles will Bahamas bobs be cheaper?
20.90 + 0.15*x < 15 + 0.20*x
x > 118 miles
Bob's place will be cheaper for more then 118 miles crossed.
