Each month Terry earns some money. He spends $120 on food and $95 on transport. He spends 2/5 of the remaining money on a new suit. He has $780 left. How much money does Terry earn in a month?

Let E be what he earns per month

 

So

 

E - 120   - 95  =

E - 215            is what he has left after   the food and  transport

 

And then he spends  (2/5) of what's left

 

(2/5)(E -215)

 

So

 

(E  -215) - (2/5) (E - 215)  = 780

 

(3/5)  (E -215)  = 780

 

E  -  215  =  780 (5/3)

 

E  - 215  =  1300

 

E =  1300 + 215  =   $1515
