Javier read a report that said the probability that a randomly selected
American is left-handed is 14%. He was curious how many left-handed
students to expect in a class of 30 students. He simulated 100 classes of
30 students where each student selected had a 0.14 probability of being
left-handed. Javier counted how many left-handed students were in each
simulated class. Here are his results. Use his results to estimate the
probability that there are 7 or more left-handed students in a class of 30
students.

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.

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
