Answer:

S = 350+70W

S =1470

Step-by-step explanation:

He starts with 350, that is the initial amount

Each week he adds 70, that means it gets multiplied by the number of weeks,W

The total amount S = the initial amount plus the weekly addition times the number of weeks

S = 350+70W

Let W =16

S = 350+70*16

S = 350+1120

S =1470
