Anyone here who can help me with this?

Mandarinka [93]

Answer:

D. 16 years old

Step-by-step explanation:

Step 1: Let T be Tien's age and J as Jordan's age (today),

$T=\frac{1}{4}J$

Step 2: Let T be Tien's age and J as Jordan's age (in 2 years),

$T+2=\frac{1}{3} (J+2)$

$T=\frac{1}{3}(J+2)-2$

Step 3: As their age differences will always be similar we can have the two equations above equal to find Jordan's age,

$\frac{1}{4} J=\frac{1}{3}(J+2)-2\\\frac{1}{4}J-\frac{1}{3}J=\frac{2}{3} -2 \\-\frac{1}{12}J= -\frac{4}{3} \\\\J=16$
