A and B originally had 6 times and 5 times as much money as C. Later, A earned another 180 yuan, and B earned another 30 yuan. The money on A was 1.5 times that of B. What is the sum of the money of A, B, and C? Use equations and formulas in two ways.
甲、乙两人原来身上的钱分别是丙身上的钱的6倍和5倍，后来甲又收入180元，乙又收入30元，甲身上的钱就是乙的1.5倍．原来甲、乙、丙三人钱数之和是多少？用方程和算式两种方法．
<gadget id="calculator">30 * 1.5</gadget>
<output>45</output>

<gadget id="calculator">180 - 45</gadget>
<output>135</output>

<gadget id="calculator">6 / 5</gadget>
<output>6/5 = around 1.2</output>

<gadget id="calculator">1.5 - (6/5)</gadget>
<output>0.3</output>

<gadget id="calculator">135 / 0.3</gadget>
<output>450</output>

<gadget id="calculator">450 * (6/5)</gadget>
<output>540</output>

<gadget id="calculator">135 / 0.3 / 5</gadget>
<output>90</output>

<gadget id="calculator">450 + 540 + 90</gadget>
<output>1_080</output>
