Answer:
Conner had 225 in the beginning
Step-by-step explanation:
Let lisa's money be L
and Conots money be C
C+L= 360----------------1
Connor gave Lisa 40% of his money,
L= 0.4C+L
C= 0.6C
L=0.4C+L=C
C=0.4C+L---------------2 <em>she had the same amount of money as he did</em>
C-0.4C=L
`0.6C=L
Put L=0.6C in eqn 1
C+0.6C= 360
1.6C= 360
C= 360/1.6
C=225
C+L= 360----------------1
225+L=360
L= 360-225
L= 135
