Question

#12 please help me solve this

Answer 1

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

Answer 2

Answer: S = 70W + C,1470

Step-by-step explanation:

S is the total amount of money, so that goes on the left side of the equation

He starts with 350, which is a constant

W is the number of weeks, and he adds 70 a week, so 70W represents the additional money he adds into the savings amount (add this to the constant)

So S = 70W + 350

Then plug in 16 as W to get

S = 70(16) + 350

S = 1470
