Ответ:
Part A: Total cost = 10 + 4s
Part B: Solving for s = 2
10 + 4 * 2 = US$ 18
Correct statement and question:
Write an expression to represent admission to a zoo of $10.00 and the cost of special exhibits s at $4 each. Evaluate your expression when s = 2.
Source: https://www.slader.com/discussion/question/write-an-expression-to-represent-admission-to-a/
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Admission to the zoo = US$ 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
