Joshua sold his bike for 10% less than he paid for it. If he sold the bike for $585, how much did he pay for it?

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
