The sales price includes the 30% mark-up on cost price. This means that the cost price is the 100% and the Sales price is 130% of the cost price. To get the cost price, we need to divide the sales price by its percentage.

Sales price : 130% $890

Cost price 100%

Mark-up on cost 30%

890 : 130% = 684.62

684.62 * 30% = 205.39

684.62 + 205.38 = 890

If you would like to calculate the cost price, you can do this using the following steps:

100% + 30% = 130%

130% of x is $890

130% * x = 890

130/100 * x = 890 / * 100/130

x = 890 * 100 / 130

x = $684.62

Result: The cost price was $684.62.
