Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Admission to the zoo = US$ 10
Special exhibit cost (s) = US$ 4
2. Evaluate your expression when s = 2
Total cost = Cost of admission + (s) * Special exhibit cost
Total cost = 10 + (s) * 4
Total cost = 10 + 4s
3. Solving for s = 2
10 + 4s
10 + 4 * 2 = US$ 18
