Toilet paper is sold in packages like 6 rolls for $2.49 and 28 rolls for $7.99
determine the unit price for each toilet paper

Step-by-step explanation:

6 rolls = $2.49

and

28 rolls = $7.99

To find unit price of each roll for the 2 packages listed above, we have to divide the total price by total number of rolls in the package.

First Package:

2.49/6 = $0.415 = $0.42 per roll

Second Package:

7.99/28 = $0.285 = $0.29 per roll

The second package is better to buy.

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
