# I need help with this problem and to see if I'm doing it right:

For the table, identify the independent and

dependent variables, Represent the relationship

using words, an equation and a graph.

# of cases of | # of bottles

bottled | of water, b

water, c |

1 | 24

2 | 48

5 | 120

10 | 240

20 | 480

So far I think:

Independent Variable is C ( # of cases of bottled water)

Dependent Variable is B ( # of bottles of water)

Because the number of bottles depends on the number of cases

And my thoughts for the equation are:

B = 24C

Thoughts?

## looks good

## What should the graph look like?

## independent is traditionally on x-axis

straight line through the origin

... no cases, no bottles

slope is 24 bottles per case

## So do I plot the dots on all of those and then connect the line?

## yes

usually, partial cases do exist

## 4. Graph the function rule. Use labels. Explain why the

graph is continuous or discrete.

The amount of money made by selling bikes depends

on the number n of bikes sold. So a = 150n.

So I need help with how to graph this and I know what discrete and continuous functions are but I don't know how I'd relate them to this equation

## It's not possible for tutors on Jiskha to help you with graphing more than Scott has already done.
