Let the cost of the dining table is 100%
∵ It sells with a 30% markup
→ That means the selling price of the table will be 100% + 30%
∴ The selling price of the table = 130% of the cost price
∵ The cost price of the table = $130
∴ The selling price of the table = 130% x 130
→ Change the percentage to a decimal by divide it by 100
∴ The selling price of the table = 1.30 x 130 = 169
∴ The selling price of the dining table is $169
