Step-by-step explanation:

Graph Reading

Line graphs are visual ways of representing two or more data sets and their interrelation.

Graphs are pictures that show how one variable changes in relation to another.

Learning to properly read graphs is a matter of interpreting which pieces of information are useful.

The graph (in the red drawing) shows how sales of ice lollies changed in time. By February, the sales were about 4 units and by August sales were up to 80 units.

This means an increase of 80 - 4 = 76 units.

The sales of ice lollies increased by 76 units between February and August

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
