The question is about the calculation of Amina's age. From the information provided, Amina's age is calculated to be 9 years 4 months. The calculation is done by first obtaining the total age before and after Amina joins then finding the difference.
Explanation:
Firstly, we know the mean age of five children, before Amina joins, is 8 years 4 months. To get the total age of these children, we multiply the mean by the number of children. So, 8 years 4 months x 5 gives 41 years 8 months in total.
Next, Amina joins, increasing the number of children to six and the mean age becomes 8 years 5 months. To get the new total age, we multiply the new mean by the total number of children, so, 8 years 5 months x 6 gives 51 years.
So, the age of Amina is found by subtracting the initial total age before she joined from the new total age after she joined, which is, 51 years - 41 years 8 months = 9 years 4 months.
Thus, Amina's age is 9 years 4 months.

Answer:
Plan A has a unit rate of approximately $0.1087 per minute.
Plan B has a unit rate of approximately $0.0700 per minute.
Step-by-step explanation:
Plan A:
38 minutes of long-distance calling
Total cost: $4.13
To find the unit rate for Plan A, divide the total cost by the number of minutes:
Unit Rate for Plan A = Total Cost / Number of Minutes
Unit Rate for Plan A = $4.13 / 38 minutes ≈ $0.1087 per minute
Plan B:
59 minutes of long-distance calling
Total cost: $4.13
To find the unit rate for Plan B, divide the total cost by the number of minutes:
Unit Rate for Plan B = Total Cost / Number of Minutes
Unit Rate for Plan B = $4.13 / 59 minutes ≈ $0.0700 per minute

She saved 20 dollars on the sweater that she bought.
Let's solve for the original price of the sweater then,
=> 20 dollars = 40%.
Let's look for the 60%.
=> 20 / 4 = 5 dollars is the 10% of the sweater's original price.
=> 5 dollars * 10 = 50 dollars
=> Thus the original price of the sweater is 50 dollars.
