Keith paid #90%# of the price of a new car for the used car.

Explanation:

To calculate that, we have to find what percentage of #40,000# is #36,000#. Considering the percentage as #x#, we write:

#40,000xxx/100=36,000#

#400cancel00xxx/(1cancel00)=36,000#

Divide both sides by #400#.

#400/400xx x=(36,000)/400#

#(1cancel400)/(1cancel400)xx x=(360cancel00)/(4cancel00)#

#x=360/4#

#x=90#

The answer is #90%#.
