Answer:
Cost of first event: $26 per person
Cost of second event: $35 per person
Cost of both events together: $61 per person
Step-by-step explanation:
In the first event, the four people spent $104, so the cost per person of this event is:
104 / 4 = $26
Each person pays $26 for this event.
For the second event, the four people spent $140, so the cost per person of this event is:
140 / 4 = $35
The cost per person to attend both events together is:
26 + 35 = $61
