Answer:

Lane sold 34 homes.

Nanda sold 102 homes.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

Nanda sold x homes

Lane sold y homes

Over the past 6 months they sold 136 homes.

This means that $x + y = 136$

Nanda sold 3 times as many homes as Lane.

This means that $x = 3y$

Replacing in the first equation:

$x + y = 136$

$3y + y = 136$

$4y = 136$

$y = \frac{136}{4} = 34$

Lane sold 34 homes.

$x = 3y = 34*3 = 102$

Nanda sold 102 homes.
