$ #7.146#

Formula is #D = P*R#

Where:
#D# = Discount Price
#P# = Original Price
#R# = Rate of Discount

Plugging All the Values:

We need to convert the 10% (Percentage to Decimal), Just simply remove the percentage sign then divide by 100. We get 10/100 = 0.10 or 0.1

#D = 7.94 * 0.10 #

#D = 0.794#

#Discounted Price# = Original Price - Discount Price

Discounted Price = 7.94 - 0.794

= $ #7.164#

#$7.15#

10% is just another way of writing #10/100#

Considering the question a bit at a time

10% of $7.94 is #10/100xx7.94 = 0.794" "# ( in dollars)

So the price after reduction is #$(7.94 - 0.794) = $7.146#

Rounding this to 2 decimal places gives

#" "$7.15#
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Doing the whole thing in one go:

#" "$7.94(1-10/100)=$7.146#
