How do you calculate a discount of 40 10 5 off 62.75 how do I times this in a calculator?

Answer 1

The easiest way is to calculate the price, not the discount. So you would multiply the price times 60% (100% - 40%). Then multiply that result times 90% (100% - 10%). Then multiply that second result by 95% (100% - 5%). The formula, using P as price, looks like this: ((P*.6) * .9) * .95 Because all the operations are multiplication, you can remove the parantheses and multiply in any sequence. So the following formula is equivalent: P (.6*.9*.95) or P * .513 So your price = 62.75 * .513 = 32.19 [which means the discount is 30.56 (62.75 - 32.19) which is the same as P * (1 - .513)]
