Answer :
To determine if John qualifies for the job, we need to find out his score as a percentage and compare it to the required 80%.
Here's how we can solve this:
1. Identify John's Score: John scored 18 out of 20 on his test.
2. Calculate the Percentage Score:
- To find the percentage, you divide the number of correct answers by the total number of questions, then multiply by 100 to convert it to a percentage.
- So, [tex]\( \text{Percentage Correct} = \left(\frac{18}{20}\right) \times 100 \)[/tex].
3. Perform the Calculation:
- [tex]\( \frac{18}{20} = 0.9 \)[/tex].
- [tex]\( 0.9 \times 100 = 90\% \)[/tex].
4. Compare to the Qualifying Score:
- John needs a score of at least 80% to qualify.
- Since John's score is 90%, he does exceed the 80% requirement.
Conclusion: Yes, John qualifies for the job with a score of 90%.
