    Answer:

    91,92,93,94,95,96,97,98,99,100 are all the grades to get above/or 90.

    Step-by-step explanation:

    Since each count as two grades then just add all possible values and divide them by 3 to get the average. We have to divide by three because 6/2 =3:

    \frac{88+90+90}{3} = 89

    \frac{88+91+91}{3} = 90

    \frac{88+92+92}{3} = 91

    \frac{88+93+93}{3} = 91

    \frac{88+94+94}{3} = 92

    \frac{88+95+95}{3} = 93

    \frac{88+96+96}{3} = 93

    \frac{88+97+97}{3} = 94

    \frac{88+98+98}{3} = 95

    \frac{88+99+99}{3} = 95

    \frac{88+100+100}{3} = 96

    Hope it Helps!
