I received the following email:I have only $2250 but I want to send two messages to the largest number of addresse worldwide. What is the largest number of addresses I can contact?
Correct answer: B. 205,000,000
- A. 123,000,000
- B. 205,000,000
- C. 2,230,000,000
- D. 32,000,000
Explanation
The correct answer is 205,000,000. To solve this, you need to consider the budget of $2,250 and the cost per message. By dividing the budget by the cost per message, you can determine the maximum number of messages that can be sent. Option B aligns with this calculation and represents the correct answer. Options A, C, and D either underestimate or overestimate the number of messages based on the given budget, making them incorrect choices.

About Scientific Reasoning
Scientific reasoning evaluates hypotheses through observations, variables, controls, measurements and experimental results. Questions involve identifying independent and dependent variables, recognising a fair test, interpreting tables or graphs, distinguishing evidence from opinion, and deciding whether data supports, rejects or leaves a hypothesis unresolved.

A cleaning solution is used to remove limescale, CaCO3, from bathroom surfaces. When the solution is sprayed onto the limescale, effervescence (fizzing) occurs and the solid limescale begins to disappear. This chemical reaction is needed because the limescale cannot be removed with water alone. Which of the following statements about this chemical reaction are correct? 1. The cleaning solution is acidic. 2. The effervescence (fizzing) is caused by the release of hydrogen gas. 3. The pH of the reacting solution will go down as the reaction proceeds. 4. The salt produced in the reaction is more soluble than CaCO3
The price for hiring a car is determined by the number of days for which it is to be hired and the number of people who will be using it. The table below shows the prices for groups of up to 5 people hiring cars for up to 7 days. Patrick is part of a group of 5 people on a holiday for 5 days. They will be going on outings each day, and had planned to hire one car for all of them for all 5 days. However, two of the group of people will only be there for the first 3 days, so an alternative is to hire one car for this period and another for the final two days. What will be the difference if they choose this alternative?
