When you write 55% you are basically writing a shortened version of <span>55100</span>
So the amount of increase is <span>55100</span> of 120. The mathematical equivalent of the word 'of' is multiply
So increase is:<span> <span>55% of 120</span><span> → <span>55100</span>×120=66</span></span>
So the new total is <span>120+66=</span>
<span>186</span>
