John must score [tex]80\%[/tex] correct on a test to qualify for a job. His score was [tex]\frac{18}{20}[/tex]. Does he qualify? What is his percent correct?

A. Yes. [tex]90\%[/tex]

B. Yes. [tex]88\%[/tex]

C. No. [tex]79\%[/tex]

D. No. [tex]50\%[/tex]

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%.
