Answer:

The equation is y=-4x+103

The slope is m=-4

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

y is the amount left in the saving account

x is the number of weeks

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value

In this problem we have

The slope is equal to

m=-\$4\ per\ week --> is negative because is a decreasing function

The y-intercept or initial value is

b=\$103

substitute

y=-4x+103

so first day and so on

7, 10, 13,....

as you can see it's an arithmetic progression

so sum for nth term= n/2 { 2a + (n-1) d}

it's the sum of the 7th term

so

7/2 { 7 ×2 + ( 7-1) 3}

7/2 × 32

7× 16

112 fishes
