Answer

Explanation:

Step1: Calculate Rosario's average

The sum of Rosario's scores is $78 + 77+64 + 86+70=375$. The average is $\frac{375}{5}=75$.

Step2: Calculate Enrique's average

The sum of Enrique's scores is $90 + 61+79+73+87 = 390$. The average is $\frac{390}{5}=78$.

Step3: Find the difference

Subtract Rosario's average from Enrique's average: $78 - 75=3$.
