Answer:
Kindly check explanation
Step-by-step explanation:
Expected cost = $50
Tip = 20% = (0.2 * $50) = $10
Round trip transportation = $15
Total cost = ($50 + $10 + $15) = $75
Benefit derived from going to dinner :
Value of meal = $30
Valuation of time spent = $50
Total value of benefit = ($30 + $50) = $80
Since, the benefits exceed the cost, $80 > $75
Then, You should __go__ to dinner with your friend because the benefit of doing so is __greater___ than the cost.
