The cost of a banquet can be calculated using the function b=75+15n where b represents the total cost and n represents the number of people attending. If the total
cost of the banquet is 130, how many people attended the banquet? (Round to the
nearest whole number)

4 people were attending the banquet

Step-by-step explanation:

1 - Rewrite

b = 75 + 15n; b = 130

2 - Plug in and get n alone

130 = 75 + 15n

- 75  -75

55 = 15n ←↓ Divide both sides by 15

55/15 = n

4
