Answer:
The lesser number of workbooks are 1,000
Step-by-step explanation:
The correct question is
The profit P (in thousands of dollars) for an educational publisher can be modeled by P=-b³+5b²+b where b is the number of workbooks printed (in thousands). Currently, the publisher prints 5000 workbooks and makes a profit of $5000. What lesser number of workbooks could the publisher print and still yield the same profit?
we have
For 
substitute in the equation and solve for b
Remember that the profit and the number of workbooks is in thousands
so
P=5

Using a graphing tool
Solve the cubic function
The solutions are
x=-1
x=1
x=5
therefore
The lesser number of workbooks are 1,000
<u><em>Verify</em></u>
For b=1
-----> is in thousands
so
----> is ok

I hope this helps you
Answer:
4650 adults
Step-by-step explanation:
The ratio of people who drink coffee to total people is 31/50, or 0.62
To find the number of adults in the town who drink coffee, multiply the ratio by how many people there are in the town.
Plugging in the values we are given,
0.62 * 7500 = 4650
We can expect 4650 adults to drink coffee in the town.
