To find the age of Rachel based on the ages provided, let's break it down step by step:
- Identify Reiki's age: Reiki is 6 years old.
- Determine Rachel's age: The problem states that Rachel is 3 years more than twice Reiki's age. To express this mathematically:
- First, calculate twice Reiki's age: 2 * Reiki's age = 2 * 6 = 12.
- Next, Rachel is 3 years more than that amount: 12 (twice Reiki's age) + 3 = 15.
So, the number expression for Rachel's age can be written as:
Rachel's Age = 2 * Reiki's Age + 3
Using the age of Reiki (6 years), it can be calculated as:
Rachel's Age = 2 * 6 + 3 = 15.
Therefore, Rachel is 15 years old.
