Natalie wants to make a 25% profit on a $70000 sale. That would be: 
(125 ÷ 100) × 70000 = $87500.
Natalie wants to make $87500. But the agent would charge a 6% for the sale, Natalie will add a 6% to the $87500, that would be:
(106 ÷ 100) * 87500 = $92750.
On this $92750, there's a closing cost of $1200, 
Add $92750 + $1200 = $93950.
$93950 to the nearest hundred will be $94000.
Natalie should make the final sale price $94000 in order to make a profit of %25.
