Since, three years from now, Tabitha will have 8 different colors in her hair, this year she has 8 - 3 = 5 colors in her hair. Since she had 2 colors in her hair at the age of 15, she has added 5 - 2 = 3 colors since she was 15 years old. Since she ads one color per year, 3 added colors = 3 added years. Thus, currently, she is 15 + 3 = 18 years old.
The answer: 18
Reverse engineering the question: Every year, Tabitha adds a new color to her hair. She started this tradition when she was 15 years old, which was the year she added her second hair color. In three years, Tabitha will have 8 different colors in the hair. Currently, how old is Tabitha?

First find the number of mice the snake eats each year: 52 weeks / year / 4 weeks / mouse = 13 mice / year. Then multiply the number of mice the snake eats per year by the number of years per decade to find the number of mice it eats per decade: 13 mice / year * 10 years / decade = 130 mice / decade.
The answer: 130
Reverse engineering the question: Gina's snake eats one mouse every 4 weeks. How many mice will it eat in a decade?

First, we need to determine how much Johnny makes in one day. To start, we perform 3 * 7 = 21 dollars for the first job. Second, we perform 2 * 10 = 20 dollars for the second job. Third, we perform 4 * 12 = 48 dollars for the third job. Altogether, Johnny makes 21 + 20 + 48 = 89 dollars in a day. We multiply this amount by the 5 days, performing 5 * 89 = 445 dollars over 5 days.
The answer: 445
Reverse engineering the question: Johnny spent 3 hours working on a job that paid $7 per hour, 2 hours working on a job that paid $10 an hour, and 4 hours working on a job that paid $12 an hour. Assuming he repeats this process 5 days in a row, how much does Johnny make?

Santo = (1 / 2) 1956 = $978. 1956 + 978 = $2934. Together Salvadore and Santo earned $2934.
The answer: 2934
Reverse engineering the question:
Salvadore earned $1956. Santo earned half of what Salvadore earned. How much money did the two men earn together?
