Answer:
48
Explanation:
for this we need to figure out the rate of change and the price for one notebook, we can take any point on the graph like 12 notebooks for $27
first divide the price by the amount of books
27 / 12 = 2.25
and BOOM step one is done, we now know the cost for one notebook, not to find out how many notebooks $108.00 will give you, we will divide again, this time we divide the goal cost by the unit cost
108.00 / 2.25 = 48
and that is the amount of notebooks that $108.00 will get ya, please comment if you have questions about the process or how it can be used in similar situations
take care mah m8s :D
