Answer:
$112.80
Step-by-step explanation:
You are buying 8 student tickets, each costing $10.68. Multiply 8 with 10.68:
10.68 x 8 = 85.44
You are buying another 2 adult tickets, each costing $13.68. Multiply 2 with 13.68:
13.68 x 2 = 27.36
Next, add the two costs together:
27.36 + 85.44 = 112.80
$112.80 is your total cost.
