Give the step-by-step reasoning process and then the final answer. When Jayson is 10 his dad is four times his age and his mom is 2 years younger than his dad. How old was Jayson's mom when he was born?
When Jayson is 10 his dad is 10 x 4 = 40 years old. His mom is 40 - 2 = 38 years old. When Jayson is born, his mom is 38 - 10 = 28 years old.
The final answer: 28.
