Depends on whether the two items are the same and costing the same amount. If so, you may add the cost of the two items or multiply the cost of one item by 2. However, if the two items are priced differently, you have no choice but to add the costs.
You simply multiply the tax rate with the item's original cost and divide by hundred, to get the tax. Then you add that to the original cost, to get the total cost. In Java you use + to add, * to multiply, and / to divide.
Multiply the pre-tax cost by 1.0775.
First you calculate the amount of the tax on the item. Then you add together the original cost of the item and the tax.
cost price multiply by profit then add the answer to the cost price =selling price
cost price multiply by profit then add the answer to the cost price =selling price
To determine the total cost of an item including tax, first convert the tax rate from a percentage to a decimal by dividing it by 100. Then, multiply the item's price by this decimal to calculate the tax amount. Finally, add the tax amount to the original price of the item to find the total cost. The formula can be summarized as: Total Cost = Price + (Price × Tax Rate).
To find the discount on an item, multiply the original price by the discount percentage (expressed as a decimal), then subtract that amount from the original price. For sales tax, multiply the original price (or the price after discount) by the sales tax rate (also as a decimal). Finally, add the sales tax to the discounted price to get the total cost.
To calculate the new price after a 35 percent markup on an item that originally costs $6.75, multiply the original price by 0.35 to find the increase: $6.75 × 0.35 = $2.36. Then, add this increase to the original price: $6.75 + $2.36 = $9.11. Therefore, the item would cost $9.11 after the markup.
you are suppose to MULTIPLY on area.
Multiply the pre-tax price by 1.065
You multiply 102.00 by 1.0775
you add the area
