Always read the question very carefully as it contains a lot of vital information's. Based on those information's the answer to the question can be easily deduced.
Total number of questions given in a Chinese test = 40
Percentage of questions incorrectly answered by Kara = 10%
Then
Number of questions incorrectly answered by Kara = (10/100) * 40
= 4
Then
The total number of questions correctly answered by Kara = 40 - 4
= 36
From the above deduction we can clearly see that Kara answered 36 questions correctly among the total of 40 Chinese questions that were given.
Answer:
No inequality given but in my view answer is:
x ≥ 16
Step-by-step explanation:
Given that:
Total time = 6 hours
Remaining Time = 6 - 2 hours = 4 hours (40*6 =240 mins)
Time required for 1 centerpiece = 15 mins
We have to find inequality for x:
Number of centerpieces she makes = x
In 240 mins : 240/15 centerpieces can be made
= 16 centerpieces
If she works with the same speed or more efficiently the suitable inequality would be:
x ≥ 16
I hope it will help you!
