The first option is a fee-for-service plan with a $7,500 deductible. Rachel must pay the deductible amount in health-related costs (not including co-pays) before the insurance company will contribute. This plan costs $225.00 per month and requires co-pays for most standard healthcare costs. The second option is an HMO. It is significantly more expensive at $630 per month, but has no annual deductible. The standard co-pays are also less than those in the other option. Rachel is a young lady with very few health care requirements. She anticipates one monthly visit to her primary care physician, and one annual visit to her allergy specialist. She has two generic prescription allergy medicines that need to be filled twice a month. If Rachel is able to stay healthy the entire year and does not accrue any additional health care costs, which of the following statements is true for her situation? a. The higher co-pays and annual deductible make Option 1 more expensive than Option 2. b. The higher premium for Option 2 offsets the lower co-pays making the two options the same value. c. Rachel's health care needs will cost less under Option 1 if she is able to avoid additional health care costs. d. Even though she pays more monthly, the insurance company will cover more of Rachel's health care costs under option 2.

Sharon wants to make a graph to show the relationship between the number of tickets sold and the price of tickets sold. She plots the following points: (0, 0), (1, 20), (2, 40), (3, 60), (4, 80) She uses the following steps to plot the graph: Label origin as (0, 0). On x-axis, label Number of tickets sold. On y-axis, label Price of tickets in dollars. The scale on x-axis starts from 0 and goes up to 10 at intervals of 2. The scale on the y-axis starts from 0 and goes up to 200 at intervals of 20. Which of the following best describes the graph? It will not be spread out across the entire coordinate plane because in Step 1, Sharon selected an incorrect point as the origin. It will not be spread out across the entire coordinate plane because in Step 2, Sharon plotted the dependent variable on the x-axis. It will not be spread out across the entire coordinate plane because in Step 3, Sharon plotted the independent variable on the y-axis. It will not be spread out across the entire coordinate plane because in Step 4 and Step 5, Sharon selected incorrect scales on the axes.
