Question

The price of an item is reduced by 30% of its original price. A week later it is reduced by 20% of the reduced price. The cashier informs you that there has been a total reduction of 23%. Is the cashier using percentages correctly? If not, what is the actual percent reduction from the original price?

Answer 1

let x be the original price

when it gets reduced by 30% you just multiply x by 70%

(0.7x) <--reduced price

now when the reduced price gets reduced by 20% you just multiply 0.7x by 80%

(0.7x)(0.8) <---new price

now... do you know what 0.7 * 0.8 is?

Answer 2

Let x be the original price

((x * .3)0.2)

Answer 3

There really has been a reduction of 56%

Answer 4

Oh, wow. I just noticed this question was asked 2 months ago. Never mind then.
