Answer: B and 7
Step-by-step explanation:
At least 175 = equal to 175 or more than 175
So a and c are out
Since he has 34 kg and has to buy more bags with 23 kg each
The answer is b
Using the inequality from choice b, we get
175 - 34 = 141
141 / 23 = 6.13
If he buys 6 bags, he will have 172 kg in total which is not enough so the answer is 7
