In this question, it is given that
Walter wants computer software that cost $129. He has $57 saved.
he saves a maximum of $15 a week, the following inequality can be used to find how many weeks it will take Walter to save enough money to buy the software.

And we have to solve this inequality for x.
First we subtract 57 to both sides. And on doing so , we will get

Dividing both sides by 15.

Correct option is A.
The correct answer answer 56
B.77.76 Sq in
I did 3.6^2 and then multiplied it by 6
Hope this helps :)
Add the numbers: 3+17 = 20
-x + 5 < -1/20
Apply the fraction rule: -a/b = - a/b
-x + 5 < - 1/20
Subtract 5 from both sides
-x + 5 - 5 < 1/20 - 5
Simplify
-x< - 101/20
Multiply both sides by -1 (reverse the inequality)
(-x) (-1) > (-101/20) (-1)
x> 101/20 is the final answer
