$400

Step-by-step explanation:

Note that 300% of $100 is $300.  We add this increase ($300) to the original amount ($100), obtaining $400.

The $100 increased by 300% by $400.

We have to determine

What is $100 increased by 300%?

Percentage;

A percentage is a number or ratio that can be expressed as a fraction of 100.

The new value is determined by;

New value = 100 + Increase  in percentage

New value = 100 + (300% × 100)

New value = 100 + 300% × 100

New value = ( 1 + 300% ) × 100

New value = (100% + 300%) × 100

New value = 400% × 100

New value = 400 ÷ 100 × 100

New value = 400 × 100 ÷ 100

New value = 40000 ÷ 100

New value = 400

Hence, the $100 increased by 300% by $400.
