-2.5

Since he already has saved more money than he needs its going to be a negative.

Step-by-step explanation:

1. Create a equation

a. The equation must equal 240 because we know that is the total Jack is saving for

b. He already has 260$ so we must add it within the equation

c. We add 8x because we know he gets 8$ a week but since we dont know how many weeks we will use the variable x

8x + 260 = 240

2. Get x by itself. Do this by subtracting 260 to both sides of the equal sign

8x = - 20

3. Divide 8 to both sides of the equal sign

x=-2.5
