So I use decimal multipliers for discounts to do this just change your percentage into a decimal with 100% as 1.00 so if it were increasing by 5% it would be 1.05 since it’s a sale the decimal would be 0.95 you can now multiply this to the original price to find this new price
So 689.99 x 0.95
If you follow this again for the 15% sale then the decimal multiplier would be 0.85
So 689.99 x 0.85
Just put these into a calculator and you’ll get your answers
