Answer 1

Using a system of equations, it is found that Teresa's password in the 7th day of the month is of 98.

What is a system of equations?

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

The rule for her password is defined as follows: A whole number that is equal to four times the fourth power of the day of the month divided by two times the square day of the month. Hence, considering n as the day of the month, the equation is given by:

$P = \frac{4n^4}{2n^2} = 2n^2$

Hence, for the 7th day, the password is given by:

P = 2 x 7² = 98.
