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.
Answer:
9 7/40
Step-by-step explanation:
3 4/5 + 5 3/8
First we need to get a common denominator of 40
3 4/5 * 8/8 = 3 32/40
5 3/8 *5/5 = 5 15/40
Add the fractions together
3 32/40+ 5 15/40
8 47/40
Rewriting
8 + 40/40 + 7/40
8 + 1+ 7/40
9 7/40
All of the choices (1 , 2 , 3 and 4) are correct
