Daniel is twice as old as Jimmy. Terry is one year younger than Daniel. If the sum of their age is 44. How old is Daniel? Click to Show/Hide Solution $\text{Let:}$ $\text{Daneil = D}$ $\text{Jimmy = J}$ $\text{Terry = T}$ \[ D = 2J; J = \frac{D}{2} \] \[ T = D - 1 \] \[ D + J + T = 44 \] \[ D + (\frac{D}{2}) + (D - 1) = 44 \] \[ D = 18 \leftarrow \text{answer} \]
