Answer:

Option (B)

Step-by-step explanation:

Group of 'n' friends is going to drive together.

Expected expenditure on gasoline and parking = $(15 + 20) = $35

Expected expenditure for lunch, tickets for museum and dinner

= (8 + 11 + 12) × n

= 31n

Expression representing total expenditure = 35 + 31n

This expression shows the expected expenditure on each friend = $31

Plus an extra expense on gasoline and parking = $35

Therefore, Option (B) is the correct option.
