Answer 2

Answer:

$700000

Explanation:

200000+Percentage increase, by the question we know that this increase is for 250%, so it would be 200000+(250%x200000).

250% is the same as 250/100 equal to 2.5.

Solving the equation by using common factor it would be (1+2.5)x200000, the one comes from the first part that is multiplied by 1.

It is the same as 3.5x200000, whose result is 700000
