Answer :
The equation expressing y, as the total number of volumes in the library, in terms of x, the number of mouths after march 2004 is y = 400x + 60,000.
What is the equation for the volumes in library?
The equation expressing y, as the total number of volumes in the library, in terms of x, the number of mouths after march 2004 is determined as follows;
Using general linear equation;
y = mx + b
where:
- y is the total number of volumes in the library
- x is number of months after March 2004
- m is the rate of change
- b is the initial number of volumes in the library in March 2004
The initial volume as at March = 60,000
the rate = 400 volumes / month
The equation is determined as;
y = 400x + 60,000
