(Work must be shown)

What is the minimum score she needs to make on the fifth test to ensure her average is at least 80%?

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:

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

x ≥ 56
