Question

A homeowner installs solar panels on both the east and west sides of their roof. 45 percent of the total energy generated by the panels comes from the east side, while the remaining 55 percent comes from the west side. The panels are connected to two separate battery banks, one for each side and all battery banks store energy at the same rate and over the same period.
 
Select for  East Side  the amount of energy stored in kWh in the East Side Battery Bank and select for  West Side  the amount of energy stored in kWh in the West Side Battery Bank that would be jointly consistent with the given information. Make only two selections, one in each column.

Official Solution:

The energy stored in the east side battery bank must be 45% of the total, while the energy stored in the west side battery bank must be 55% of the total.
 
This corresponds to a ratio of 45:55, which simplifies to 9:11.
 
Among the given values, only the pair 9 kWh for the east side and 11 kWh for the west side maintains this ratio.

Correct answer:

East Side  "9"

West Side  "11"
