Question

Ross and 5 of his friends are going kayaking. They rented 6 kayaks for $420. Then they bought food for all 6 people, which cost $144. If all 6 people shared the cost of the trip equally, how much did each person pay?

Answer 1

The answer is $94

n - the number of people
t - total cost

n = 6
Total cost is the sum of cost for kayaks and cost for food:
t = 420 + 144 = $564

Each person paid:
t/n = $564/6 = $94
