Hello ;
<span>an = 1 • 3n - 1</span>
Sorry I don’t have a calculator with me atm but if you just put this into a calculator you’ll have the answer
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
8x - 12 = 4x
8x - 4x = 12
4x = 12
x = 12/4
x = 3
