ITS OPTION 3
Step-by-step explanation:
Find the number ofhours each person worked.
x = Isaac hours
x + 4 = Ruby hours
((x + 4) * 4) = Svetlana hours
104 = x + (x + 4) + ((x + 4) * 4)
104 = 2x + 4 + 4x + 16
104 = 6x +20
104 - 20 = 6x + 20 - 20
84 = 6x
x = 14 hours
so
x = Isaac hours = 14
x + 4 = Ruby hours = 14 + 4 = 18
((x + 4) * 4) = Svetlana hours = ((x + 4) * 4) =18 * 4 = 72
Prooff: 14 +18 + 72 = 104
