Answer 2

Answer: 16

Step-by-step explanation:

we have: Mean1(average1) = Sum of grapes / n(bowls)

THEN we have: Mean2(average 2) = Sum of grapes + 12 x 8 / n(bowls)

which: Mean2(average 2) = Sum of grapes / n( bowls)  +  96(12x8) / n(bowls)

Also the question said the mean (average) number of grapes per bowl increased by 6.

So: Mean1(average1) + 6

but we all know that Mean1 is equal to = Sum of grapes / n(bowls)

====> Mean1(average1) + 6 = Sum of grapes / n(bowls) + 6

Also we can know that: Mean1(average1) + 6 = Mean2(average 2)

So we have: Sum of grapes / n + 6 = Sum of grapes / n  +  96 / n

which mean: 6 = 96 /n

==> n(bowls) = 96:6

==> n(bowls) = 16
