Answer:
$295
Step-by-step explanation:
Let d represent the amount Danny contributed. Then Beth contributed (d+80) and Katie contributed ((d+80)-20) = (d+60). The total from the three friends is ...
d + (d+80) +(d+60) = $1025
3d = 885 . . . . . . . . . . . . . . . . . . . subtract 140
d = 295 . . . . . . . . . . . . . . . . . . . . divide by 3; Danny's contribution
Danny contributed $295.
