48/19 = avg expenditure before 19 ppl left and add 5 to that multiply by the number of ppl left

anonymous · Answer

2.52+5*19=97.52

anonymous · Answer

36(x+5)=17x-48,
36x+180=17x-48
x=6.9

anonymous · Answer

36*6.9=252.10 is the original exp
17*(5+6.9)=202.3is the new exp
so 452.3 is the ans i think
