the original price of the camcorder is $7,680
(steps/work below)
First, you want to make it into an equation
(original price) - (25% of original proce) = total paid
LETS MAKE THIS SIMPLE BY USING VARIABLES!
original price = x
25% of original price = 0.25x
total paid = 5,760
Rewrite our new equation.
x - 0.25x = 5,760
now lets solve
to get the "x" alone on both sides we can divide by 0.75
x=7680
the original price of the camcorder is $7,680
plug in numbers to variables to check your work
7680 - 0.25(7680) = 5760
7680 - 1920 = 5760
