1. <u>Too broad:</u> what will the economy be like in the future?
2. <u>Effective:</u> how can virtual reality (VR) be used in health care?
3. <u>Too narrow:</u> how many gallons of water will we use in 2025?
4. <u>Effective:</u> what are the best strategies for <u>increasing</u> food production in the future?
A research question can be defined as a specific inquiry (question) that a research work seeks to provide an answer or response to, especially by using scientific methods such as the following:
- Documenting critical information.
According to their nature, a research question is broadly classified as follows:
1. <u>Too broad:</u> what will the economy be like in the future?
- A country's economy has many facets and as such it would be difficult to write about what it would be like in the future in one research paper.
2. <u>Effective:</u> how can virtual reality (VR) be used in health care?
- Virtual reality (VR) is a modern technology that is effectively used by medical professionals in the field of medicine to provide health care for various patients.
3. <u>Too narrow:</u> how many gallons of water will we use in 2025?

Answer:
The equation that could be used for determining the y should be option B y = 20x + 75
Calculation of an equation:
Since dad gave him 75 coins. each month he will add 20 coins.
