248

Step-by-step explanation:

"Eric has 12 bags of green marbles with 8 in each bag."

12 * 8 = 96

Eric has 96 green marbles.

"Then he bought 7 bags of blue marbles. There were 4 blue marbles in each bag."

7 * 4 = 28

Eric has 28 blue marbles.

The total number of marbles Eric has:

96 + 28 = 124

"Eric's brother has twice as many marbles as Eric."

2 * 124 = 248

"How much marbles does his brother have?"

248
