on his last four tests, Danilo scored 55%,78%,84%,and 93%. what score should he get on the next test so that his average on all five tests is 80%



Answer :

Answer:

90%

Step-by-step explanation:

Let's denote the score he should get on the next test as "x".

[tex]\frac{55+78+84+93+x}{5}[/tex] = 80%

310 + x = 400%

x = 90%

So, Danilo should aim to score 90% on the next test in order to have an average of 80% across all five tests.
