Question

The price of a printer increased by 8% to $777.60. Find the original price of the printer.

Answer 1

1.08x=777.60, 777.60/1.08=720

Answer 2

$720

Explanation:

If it increased by 8% you would have multiplied the original value by 1.08 since you are keeping the original value by increasing by 8% (0.08). Therefore your equation would have looked like:

x * 1.08 = 777.60

To solve you need to get the x standing alone so divide by 1.08.

x = 720
