Question

Hi, I'm having a lot of trouble with this one problem and I really need help. Thanks!

Charlie wants to compare bike rental companies while he is on vacation. Handlebar Mania has a flat rate of $50 for all day. Peddle-Me-Faster has no initial charge, but it is $10 per hour. Two-Wheelin' only charges $5 per hour, but it has an initial charge of $20.

Explain to Charlie how he can graph these bike rental charges and describe what key features of the graphs he should consider when making a decision.

Answer 1

Say x is the number of hours you rent the bike and y what it costs you. The equations for the graphs will be :
For Handlebar Mania: y=50
For Peddle-Me-Faster: y=10x
For Two-Wheelin': y=5x+20
When you see the graphs the key features you wanna look for are where the graphs meet.
