Answer:

$575

Explanation:

So we know the function is f(x)=35x+120 so we use that to find our answer.

Though theres a trick to it, it says how much money is spent in 12 months, but our table starts from 0 months.

The table states the variable X represents the momths and f(x) represents the money spent.

So the (35x) - x variable will be the number of months we need to look for which is 12. But since we start at 0, it will be shifted to 13 since 0 is an extra number.

Our equation now is f(x)= 35 (13) + 120

We need to find f(x) which is now simple: 35 x 13 is 455, plus 120 is 575.

f(x)= $575
