Routeros and repeater

I would like to know if this is likely to work.

DSL ->750up (config for l/p limit 1gb of data) ->AP (200ft to the) ->AP- repeater (then 75ft to) ->user laptop

I’m not sure if the repeater will be a hindrance to the router l/p.

Only 5 users
I don’t need massive bandwidth
I don’t need more then 200ft
I need reliable and cheap.

repeater means 1/2 trougput
