A family of four spent $104 for tickets to a concert on Friday and they spent $140 for tickets to dinner theater on Saturday. What was the cost per person to attend these events

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

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
