Adam have $1200 at 1st
Please help with the working. Thanks
At 1st...
B= 8u
C= 5u
A= 2500-13u
After ...
B= 4u
C= 5u
A= ½(2500-13u)
After total = 1500
4u+5u+½(2500-13u)=1500
9u + ½ (2500-13u) = 1500
9u×2 + ½×2 (2500-13u) = 1500×2
18u + 2500 - 13u = 3000
5u = 500
1u = 100
Adam at 1st = 2500 -13u
= 2500 - 13×100
= 2500 - 1300
=$1200
B= 8u
C= 5u
A= 2500-13u
After ...
B= 4u
C= 5u
A= ½(2500-13u)
After total = 1500
4u+5u+½(2500-13u)=1500
9u + ½ (2500-13u) = 1500
9u×2 + ½×2 (2500-13u) = 1500×2
18u + 2500 - 13u = 3000
5u = 500
1u = 100
Adam at 1st = 2500 -13u
= 2500 - 13×100
= 2500 - 1300
=$1200
