Step-by-step explanation:

<u>Step 1: Define</u>

9m - m + 3 = -2(m + 1)

<u>Step 2: Solve for </u><em><u>m</u></em>

  1. Combine like terms:                    8m + 3 = -2(m + 1)
  2. Distribute -2:                                8m + 3 = -2m - 2
  3. Add 2m on both sides:                10m + 3 = -2
  4. Isolate <em>m</em> term:                             10m = -5
  5. Isolate <em>m</em>:                                      m = -1/2

100% - 49%

= 51%

We don't actually have enough information to determine the percents for summer and winter. BUT the only answer that adds up to 51% is answer D. 29% and 22%.
