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.
First you calculate the amount of the tax on the item. Then you add together the original cost of the item and the tax.
Multiply the pre-tax cost by 1.0775.
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
you are suppose to MULTIPLY on area.
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.
Multiply the pre-tax price by 1.065
You multiply 102.00 by 1.0775
you add the area
You have to multiply to find area you have to add to find perimiter
