The minimum score Jasmine needs to make on the fifth test to ensure her average is at least 80% is 56%

Step-by-step explanation:

This is the information provided to us to answer the question correctly:

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

x ≥ 56
