Reasoning and answer: Since the word score after being tripled was 30 points, then the word score before tripling was 30 / 3 = 10 points. If before the word score was tripled, the first and third letters were each valued at one point apiece, then the value of the middle letter was 10 - 1 - 1 = 8 points.
The answer: 8

Question: Jeremy loves to play Scrabble. He once played a three-letter word on a triple word score to earn thirty points. If before the word score was tripled, the first and third letters were each valued at one point apiece, how much was the middle letter valued at before the word score was tripled?

Reasoning and answer: He used 5 * 2 = 10 wigs per play. So in total, he used 10 * 3 = 30 wigs. They cost 30 * 5 = $150. He gets back 10 * 4 = $40 from selling the wigs. So he spent 150 - 40 = $110.
The answer: 110

Reasoning and answer: Since 80% of the people were adults, this means 100% - 80% = 20 % were children. 20% of the people vaccinated were children. The number of children is 20% of 650. 20% = 0.2, so 0.2 * 650 = 130 children were vaccinated.
The answer: 130
