Answer:
<u>The minimum score Jasmine needs to make on the fifth test to ensure her average is at least 80% is 56%</u>
Step-by-step explanation:
This is the information provided to us to answer the question correctly:
- Score 1st test = 87%
- Score 2nd test = 92%
- Score 3rd test = 76%
- Score 4th test = 89%
- Score 5th test = x
Now, let's calculate the average of Jasmine's scores and to solve for x:
(87 + 92 + 76 + 89 + x)/5 ≥ 80
(344 + x)/5 ≥ 80
344 + x ≥ 80 * 5
344 + x ≥ 400
x ≥ 400 - 344
<u>x ≥ 56</u>
