1st
40% of the original amount (a) is given to the mother
30% out of the remainder = the remainder is now 100%

Using the remainder left as 60%
30%x60 = 18%
So magazine is 18% out of the original amount (a)

Find the left over is 42%
50%=1/2
1/2 of the 42% is how much he spend on food

40%-21%= $95
