The amounts that two partners invested in a new business are given below. If the partners share the profits in the same ratio as their investment, what is partner B's share in a $3600 profit?

Partner A $4300 Partner B $7700

The total amount of investment = 4300 + 7700 = $12,000

Now, the percentage of share of partner B can be calculated as follows:

% of share of B = (7700/12000) x 100 = 64.1667%

Therefore, for a profit of $3600, partner B will get:

0.641667 x 3600 = $2310
