Astudent spends the same amount each week for bus fare. in 5 weeks, he spends $115. write an equation for his relationship. let x = number of weeks

f(x) = ($23/week)(x)

Step-by-step explanation:

Hello!

Let's determine the unit rate.  I'd suggest finding the cost per week, rather than the weeks covered by a certain amount of money.

Then:

$115

= $23 per week

Then the amount spent as a function of the # of weeks would be:

f(x) = ($23/week)(x)
