Answer:
[tex]20[/tex] weeks and [tex]\$1200[/tex]
Step-by-step explanation:
Let us suppose their earning will be same in [tex]x[/tex]
so basis the given information,
[tex]800 + 20x = 600 + 30x[/tex]
⇒[tex]800 - 600 = 30x - 20x[/tex]
⇒[tex]200 = 10x[/tex]
⇒[tex]x = 20[/tex]
∴ earnings of Thomas and Ken will be same in [tex]20[/tex] weeks
Amount for Thomas and Ken will be-
[tex]800 + 20(20) = 600 + 30(20)\\800 + 400 = 600 + 600 = 1200[/tex]
Their earning will be [tex]\$1200[/tex]
