Question

The amount of money Jerome saves after w weeks is represented by the function f(w)=15w+230.

What does the value 15 represent in this situation?



Each week, the amount saved increases by $15.
The total amount saved after w weeks is $15.
The initial amount saved is $15.
Each week, the amount saved decreases by $15.

Answer 1

week 1, f(1) = 15(1) + 230

week 2 f(2) = 15(2) + 230

week 3 f(3) = 15(3) + 230

week w f(w) = 15(x) + 230

"w" is how much he's saving every passing week. There's a 230 pegged to the end, that's just how much he initially had in the piggy bank.

Answer 2

Each week, the amount saved increases by $15. This is 100% correct. Trust me on this.
