I understand the instructions and will distribute the points in a way that maximizes the total earned for both participants. Here is how I would allocate the points:
KEEP account: 0 points
GIVE account: 10 points
By allocating all 10 points to the GIVE account, both participants will receive 15 points after the 50% multiplier is applied (10 * 1.5 / 2 = 15). This results in the highest total score compared to any other allocation.
