A farmer needs to spread fertiliser over a paddock measuring 40m by 80m. The instructions on the fertiliser bag say to use 80grams per square meter. How many kilograms of fertiliser will be needed?
If you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where it is more likely to be overlooked. Also, many tutors will assume the previous question has already been answered.
To calculate the expected cost of the home entertainment unit in a year's time, we need to consider the inflation rate. Inflation refers to the increase in the general level of prices over a period of time, causing the purchasing power of currency to decrease. In this case, the inflation rate for Newtopia is 15%.
A) To find the expected cost of the home entertainment unit in a year's time, we can use the formula:
Expected cost = Initial cost + (Inflation rate * Initial cost)
Given that the initial cost is $2000 and the inflation rate is 15%, we can substitute these values into the formula:
Expected cost = $2000 + (0.15 * $2000)
Expected cost = $2000 + $300
Expected cost = $2300
Therefore, you would expect the home entertainment unit to cost $2300 in a year's time.
B) Similarly, to find the expected cost of the home entertainment unit in two years' time, we can use the same formula:
Expected cost = Initial cost + (Inflation rate * Initial cost)
Given that the initial cost is $2000 and the inflation rate is 15%, we can substitute these values into the formula:
Expected cost = $2000 + (0.15 * $2000)
Expected cost = $2000 + $300
Expected cost = $2300
Now, we can use the expected cost from one year and calculate the expected cost for the second year:
Expected cost in two years = Expected cost in one year + (Inflation rate * Expected cost in one year)
Expected cost in two years = $2300 + (0.15 * $2300)
Expected cost in two years = $2300 + $345
Expected cost in two years = $2645
Therefore, you would expect the home entertainment unit to cost $2645 in two years' time.
