What’s the question asking?
Answer:
Adult tickets = $73.5
Child tickets = $20.5
Step-by-step explanation:

• Subtract eqn 2 from eqn 1:



and 10.6 is already written as a decimal.
1 meter is greater then 83 cm Because if you divide it will be 0.83 and the differences will be 0.17
Using the probability concept, it is found that there is a 0.3 = 30% experimental probability that Christine will randomly choose a page that is divisible by 3.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In an experimental probability, these number of outcomes are taken from previous trials.
In this problem:
- The experiment was made 20 times.
- Of those, in 6 experiments(81, 105, 171, 159, 297, 387) she choose a page that was divisible by 3.
Then:

0.3 = 30% experimental probability that Christine will randomly choose a page that is divisible by 3.
