This situation can be represented by the function f(x)=1000+150x.
Linear Equation can be defined as the equation that have highest degree 1.
For Example : 3x+6 is a linear equation as it's highest degree is 1.
In the given question
Total money saved=initial amount+(money saved per week)*(number of weeks) …(1)
Given that
Jessica already saved = $1000
money to be saved per week = $150
let the number of weeks she will be saving money =x
let f(x) be the function used to represent money saved
Substituting the values in eqn (1) we get
f(x)=1000+150(x)
Therefore , this situation can be represented by the function f(x)=1000+150x.
