Answer:

  B.  $10. 50

Step-by-step explanation:

You want the evenly-split cost of 5 tickets at $8.50, 5 drinks at $3.50, and 3 discount coupons with a value of $2.50.

Each share

We can add up the costs and divide by 5 to find the value of each share:

  share = (ticket cost + drink cost - coupon value) ÷ 5

  share = (5×$8.50 +5×3.50 -3×2.50) ÷ 5

  = $8.50 +3.50 -3×0.50 = $12.00 -1.50 = $10.50

Each person spent $10.50.
