Answer:
Take 1/4 of the number and that's it
Answer:
3 people attended the banquet
Step-by-step explanation:
The function is given as:
b = 75 + 15n where
b represents the total = 122
n represents the number of people attending = ??
If the total cost of the banquet is 122, how many people attended the banquet?
Hence,
122 = 75 + 15n
122 - 75 = 15n
47 = 15n
Divide both sides by 15
n = 47/15
n = 3.1333333333
Approximately to the nearest whole number = 3
Therefore, 3 people attended the banquet.
<u>a = b + c/d</u>
Subtract 'b' from each side: a - b = c/d
Multiply each side by 'd' : <em>d (a - b) = c
</em>
6x+8=100
6x=92
X= 15.33 or x =15 1/3
