See a solution process below:

Calculate The Discount

We can write this problem as: What is 40% of $99.00?

"Percent" or "%" means "out of 100" or "per 100", Therefore 40% can be written as #40/100#.

When dealing with percents the word "of" means "times" or "to multiply".

Finally, lets call the discount amount we are looking for "d".

Putting this altogether we can write this equation and solve for #d# while keeping the equation balanced:

#d = 40/100 xx $99.00#

#d = ($3960)/100#

#d = $39.60#

The discount would be: $39.60

Calculate Sales Price

After calculating the discount we can subtract the discount from the original price of $99.00 to give the sales price we can call #s#:

#s = $99.00 - $39.60#

#s = $59.40#

The sales price after the 40% discount is $59.40

#99/100 xx 40%#

#= $39.60# amount of discount

#$99-$39.60#

#=$59.40# sale price
