x > 14
The hole is open at 14 since it is greater than
( it would be closed if it were ≥) The line goes to the right since it is greater than
To get an average score of 80% (out of four exams), a total of 4*80%=320% is needed, so the minimum required for the 4th test is 320-(75+97+60)=88.
To get an average score of 89% (out of four exams), a total of 4*89%=356% is needed, so the maximum required for the 4th test is 356-(75+97+60)=124, which is impossible.
So the next exam grade must range between 88 and 100 to get a grade b in the class.

Answer:
Step-by-step explanation:
<u>Mark</u>
- Initial amount - $200
- Earning - $20*j
- Saving is: S = 20j + 200
<u>Ryan</u>
- Initial amount - $350
- Earning - $15*j
- Saving is: S = 15j + 350
<u>If they get same saving, then the equations will be equal:</u>
- 20j + 200 = 15j + 350
- 20j - 15j = 350 - 200
- 5j = 150
- j = 150/5
- j = 30
The answer is 30 mowing jobs
