Question

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

I need someone to walk me through it c:

Answer 2

Ok, here's the thing. Make your y-axis your cost axis and your x-axis your hours axis. The Handlebar Mania place does not chnge price all day, so that is a straight line at y = 50 (horizontal line at 50). Set your x-axis to individual hours, 1, 2, 3, 4, etc and set your y-axis to $10 increments. So your first line is graphed. The second line increases $10 per hour, so that line is at x = y, which starts at the (0, 0) origin and at x = 1 hour, y = 10; when x = 2 hours, y = 20; when x = 3 hours, y = 30, etc. For the last line, since the starting rate is $20, your graph starts at (0, 20) and goes up $5 for every hour. So your coordinates for the third line are (0, 20), (1, 25), (2, 30), (3, 35), etc. Does this help? Do you need the exact equations of the last line? The first is y = 50, and the second is x = y.

Answer 3

So then, the Handlebar mania line is flat, no slope? And intercepting at 50?

Answer 4

and then for the Peddle Me faster, it will have the slope of 1 and the intercept of 10? (so like y=x+10)

Answer 5

Oh wait for Peddle me Faster it would start at the origin... is the slope still 1 (because of the hour?

Answer 7

Im confused about the peddle me faster and how he would use the graph, thats it now
