Answer:

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)

Anestetic [448]

Answer:

remember,a percent means "per 100".You can describe the change as a fraction comparing the amount of change to the original and then use a proportion to rewrite your problem as a percentage out of 100.
