Which equation represents this situation?
charlie worked 1.5 hours less than dirk. together, they worked a total of 25 hours. dirk worked h hours.
oh-1.5 = 25
h + (n + 1.5) = 25
oh-2.5 = 25
h + (n - 1.5) = 25

dirk =13.25 hours

charlie =11 75 hours

Step-by-step explanation:

c+d=25(1)

d-1.5=c(2)

from (1),

c+d=25

c=25-d(3)

substitude (3) into (2)

d-1.5=c

d-1.5=25-d

2d=26.5

d=13.25

if d=13.25 hours

c+d=25

c+13.25=25

c=25-13.25

c=11.75

answer is c
