The cost of a gym membership is $75 plus $30 per month. the equation thatrepresents this relation is y = 30x + 75, where x is the number of months andthe cost. Find and interpret f(12). *

Answer 1

the equation that represent the cost of the gym in the tiem is:

`y=30x+75`

where y is the final cost, and x are the months that have passed so:

`\begin{gathered} f(12)=30(12)+75 \\ f(12)=435 \end{gathered}`

this means that in one year or in 12 months he has to pay $435 dollars
