Answer:

99

Explanation:

b) Use your answer from part (a) to write a ratio equal to 8/3.

A/B = (7x -5)/(2x +5) = 8/3

3(7x -5) = 8(2x +5)

21x -15 = 16x +40

5x = 55

x = 11

The total number of counters is 7x+2x = 9x = 9·11 = 99.

There are 99 counters in the two bags.

Additional comment

The original distribution was A=77, B=22. After moving 5, the distribution was A=72, B=27. The ratio 72/27 = 8/3, as required.
