9. Ms. Barton determined that the
total cost of her wedding, c,
could be represented by the
equation c = 75n + 1500, where n
is the number of people
attending the wedding. If Ms.
Barton's wedding cost $8625,
how many people attended the
wedding?
A 135 B 95
C 115 D 75

Respuesta :

Answer:

B. 95

Step-by-step explanation:

Plug in 8625 into the equation as c:

c = 75n + 1500

8625 = 75n + 1500

Solve for n:

7125 = 75n

95 = n

So, 95 people attended.

Answer:

B

Step-by-step explanation:

So we have the equation:

[tex]c=75n+1500[/tex]

Where c represents the wedding cost and n represents the number of people who attended the wedding.

We know that the wedding cost a total of $8625. Thus, we can plug this number in for c and solve for n:

[tex]8625=75n+1500[/tex]

Subtract 1500 from both sides. The right cancels:

[tex](8625)-1500=(75n+1500)-1500\\7125=75n[/tex]

Now divide both sides by 75:

[tex](7125)/75=(75n)/75\\n=95[/tex]

Thus, a total of 95 people attended the wedding.
