Each weekly allowance is of $63.46.What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
Removing the allowances, the taxable amount is:
390.50 - 2 x 63.46 = $263.58.
Hence, applying the rates, the withheld amount is given by:
14.40 + 0.15(263.58 - 195) = $29.69.

A student takes out 2 loans to pay for college. One loan at 9% interest and the other at 12% interest.
The total amount borrowed is $65,000, and the interest after 1 year for both loans is $6,360.
Find the amount of each loan.
The loan amount at 9% interest is $48,000.
The loan amount at 12% interest is $17,000
What are the loan amounts?The first step is to form a system of equations that can be used to determine the required values:
0.09a + 0.12b = $6,360 equation 1
a + b = $65,000 equation 2
Where:
a = amount of the loan at 9% interest
b = amount of the loan at 12% interest
What is each loan amount?Multiply equation 2 by 0.09
0.09a + 0.09b = 5850 equation 3
Subtract equation 3 from equation 2
0.03b = 510
Divide both sides of the equation by 0.03
b = 510 / 0.03
b = $17,000
Subtract 17,000 from 65,000
a = 65,000 - 17,000
a = $48,000

0.8x = 84
x = 84/0.8
x = 105.
Hence Diana and Elsa paid $105 altogether.

The account balance of each of three children at the end of a month is shown below:
Kyle has −$2.25
Jason has −$2.00
Sue has as much savings in her account as the amount Kyle owes the bank.
Part A: On a blank paper, draw a number line from −4 to +4. Plot points on the number line to show the account balances of the three children. Label the points using the name of each child. Describe in detail how you created and labeled this number line, and what it looks like in detail. (5 points)
Part B: Determine whether Kyle or Jason owes the bank more. Use absolute values and inequalities to write statements that justify your conclusion. (5 points)
The drawing of the number line representing the bank balances is attached below . Kyle owes the bank more money than Jason.
The number line a physical representation of all real numbers. A number line is basically a graph of all real numbers. A number line is a representation of a graduated straight line that is used to represent real numbers visually. It is assumed that every point on a number line corresponds to a real number, and that every real number corresponds to a point.
On the number line all the values of the bank balances of the 3 siblings are given.
Kyle owes the bank $2.25 , therefore Sue has $2.25 in her bank account.
Now we can see in the number line that -2.25 is to the left of -2.0 ,
therefore we can say that:
|-2.25| > |-2.00|
as the absolute value of the given balance .
But -2.25 < -2.00
Hence Kyle owes more money to the bank as represented on the number line.
