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.
[tex] 15x+57 \geq 129 [/tex]
And we have to solve this inequality for x.
First we subtract 57 to both sides. And on doing so , we will get
[tex] 15x\geq 72 [/tex]
Dividing both sides by 15.
[tex] x \geq 4.8 [/tex]\
Correct option is A.
