Answer 2

Answer:

there are 4 week to have $175

Step-by-step explanation:

given data

bank account = $85

deposit = $8

payback = $15

b = 85+(15+8)w

to find out

How many weeks have $175

solution

use given equation here

b = 85+(15+8)w

put value of w 1 , 2 , 3 , 4 .......... till we get 175

b = 85+(15+8)1

b = 108

b = 85+(15+8)2

b = 131

b = 85+(15+8)3

b = 154

b = 85+(15+8)4

b =  177

so we get here 177

so there are 4 week to have $175
