Gina wants to ride bikes and the waves at flagship pier in galveston. she rents a surfboard and a bicycle for 2 hours each. the surfboard costs $25 per hour, and she spends $80 total. how much per hour does the bicycle cost?

Surfboard= 25 per hour, she rent it for 2 hour so now she spent $50 on the surfboard .. now subtract how much she spends all together and how much she spent so far (80-50=30) now divide that by 2 (30/2=15) so for each hour she spends 15 for the bicycle 

If is was sunny on thursday, chances are that it will be a sunny if friday depending on the degrees and temperature. your welcome!
