Answer the following question, with explanation first.
At the family reunion, everyone ate too much food and gained weight. Orlando gained 5 pounds. Jose gained two pounds more than twice what Orlando gained. Fernando gained 3 pounds less than half of what Jose gained. How much weight, in pounds, did the three family members gain at their reunion?

20
Twice what Orlando gained is 2 * 5 = 10 pounds.

Jose gained two pounds more than twice what Orlando gained for a total of 2 + 10 = 12 pounds.

.

Half of what Jose gained is 12 / 2 = 6 pounds.

Fernando gained 3 pounds less than half of what Jose gained, for a total of 6 - 3 = 3 pounds.

In total, the three family members gained 5 + 12 + 3 = 20 pounds at the reunion.

.

The final answer: 20
