Answer:

D. 16 years old

Step-by-step explanation:

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

T=\frac{1}{4}J

<u>Step 2:</u> 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

<u>Step 3:</u> 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

I used a graphing calculator for this.

The solution my calculator got was:

(-2.625, 0.688) My calculator is very accurate, I don't think the test expects it to be like that.

Let's find the closest coordinates.

"B" is the closest.

I hope this helps!
