The required linear equation is: 60 + 7.60b = m.
The student can buy 5 books.
What is a linear equation?
A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. When this equation is graphed, it always results in a straight line.
Given, college bookstore charge $60 for a yearly membership.
Books will cost $7.60 each.
m = the money a student spend for buying books in a year.
Let, a student purchased 'b' number of books in a year.
Therefore the required equation will be:
60 + 7.60 × b = m
⇒ 60 + 7.60b = m
⇒ 7.60b = (m - 60)
⇒ b = (m - 60) / 7.60
Now, a student had $100.
Therefore, number of books the student can buy
= b
= (m - 60) / 7.60
= (100 - 60) / 7.60
= 40 / 7.60
= 5.26
≈ 5
Therefore, the student can buy 5 books.
