Answer 1

Given:
60% of what he earns is for spending. 
40% of what he earns is for savings.

n = earnings
r = savings

r = n(100-60%)

r = 109 (40%) = 43.60
r = 200 (40%) = 80.00
r = 400 (40%) = 160.00
r = 500 (40%) = 200.00

   n           r
109       43.60
200       80.00
400     160.00
500     200.00
