Answer:
He paid $ 531.8 for it
Step-by-step explanation:
Given that Joshua sold his bike for $585
Since he sold it for 10% less than he paid for it, let the amount he paid for it be x.
Then
x= $585 -(10 % of x)
=$585 - (0.1 x)
Add 0.1x to both sides
(1+0.1)x=585
1.1x=585
Divide both sides by 1.1
x=585/1.1
=531.8
