Answer 1

Answer:

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

Step-by-step 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.

Answer 2

88 + 89 + 79 + 77 = 333. 420-333= 87. The minimum score he can get is 87
