Vinh must get 87 in the next test to maintain grade B.

Explanation:

Vinh needs 420 points to have a B average in math.

His scores so far are 88, 89, 79, and 77.

Addition of these scores is =
`88+89+79+77=333`

Therefore, the minimum score he can make on the next test to maintain the grade B is :

`420-333=87`

Hence, Vinh must get 87 in the next test to maintain grade B.
