Answer:

You now pay $90 for an item that used to cost $150.

Explanation:

Let's call the price we are looking for #p#.

We can then write an equation to calculate #p# as the original price ($150) less 40% of the original price (40% of $150) or:

#p = 150 - (40% of 150)

"Percent" or "%" means "out of 100" or "per 100", Therefore 40% can be written as #40/100#. Also, when dealing with percents the word "of" means "times" or "to multiply".

Therefore we can rewrite our equation and solve for #p# while keeping the equation balanced:

#p = 150 - (40/100 * 150)#

#p = 150 - (6000/100)#

#p = 150 - 60#

#p = 90#
