Answer:
Then, it costs $2120 to order 1000 pens and 2000 notebooks.
Step-by-step explanation:
The Students' Union needs to order 1000 pens and 2000 notebooks. The price per pen when buying 1000 of them is 60c. The price per notebook when buying 2000 of them is 76c.
Then the total of money needed to order 1000 pens and 2000 notebooks is:
Total Money = 1000 × 0.60 + 2000 × 0.76 = $2120
Then, it costs $2120 to order 1000 pens and 2000 notebooks.

Take some trinomial expansions to find some useful expressions and their values.
• 2nd degree expansion
• 3rd degree expansion
• 4th degree expansion
Simplify:
Then the equation we got from the 4th degree expansion reduces to
and all we need now is the value of 
.
In the 3rd degree expansion, we have
So, we end up with
Let x = number of students then by proportion:-
5/7 = 185 / x
x = (7 * 185) / 5
= 259 Answer
The answer is C. 1/3 represents the slope and -3 represents the y intercept.
