This problem involves two unknowns, thus, it can be solved using two independent equations. We first assign a variable for each real number.
Let:
x = first real number
y = second real number
Two independent equations must then be set up which will come from the problem statement. The first equation is obtained from the statement that the average of the two real numbers is 41.375. The second equation then shows that the product of the two real numbers is equal to 1668. The equations are then:
(1) (x + y)/2 = 41.375
(2) x*y = 1668
We then express the variable y in terms of x, such that, y = 1668/x. This is then applied in equation 1 in order to have only a single variable in the equation. After doing mathematical operations, x is then calculated to be 34.75. This value of x is then substituted in the second equation to obtain y. Finally, the two real numbers have been determined to be x = 34.75 and y = 48.
The total amount of money (y) paid by Lauryn at the end of each month (x) is given by: y = 20x
Here, x is the independent variable which represent the number of months Lauryn has paid the money.
The dependent variable is y which represent the amount of money Lauryn has paid at the end of that month.
