A person is earning 750 pesos per day to do a certain job. Express the total salary(S) as a function of the number (N) of days that the person works.

The total salary (S) can be expressed as a function of the number of days (N) worked by multiplying the daily salary of 750 pesos by the number of days worked, N:

S(N) = 750 N

To express the total salary (S) as a function of the number (N) of days that the person works, you can use the formula:

S = 750 pesos/day * N days

Therefore, the total salary (S) can be expressed as:

S(N) = 750N

In this equation, N represents the number of days the person works, and S(N) represents the total salary earned after working for N days.
