Mike works part time to earn spending money and to save for college. Each month he saves 1/3 of his earnings, spends 1/5 of his earnings on eating out and spends 1/6 on transportation. The remainder will be used for entertainment. Last month he spent $45 on entertainment. How much did he earn last month.
------
Let his monthly earnings be "x".
------
Equation:
x - (x/3) - (x/5) - (x/6) = 45
30x - 10x - 6x - 5x = 45
-----
9x = 45*30
---------------
x = 5*30 = $150
