1. While you are in the shop, you find that Item 1 which was initially
discounted to 30% off the original price has a further 10% discount for
one hour. You hear a customer say: This is fantastic!! You get 40% off
the original price.
Explain why this statement is true/false, showing all appropriate
working out.

This statement is False

Step-by-step explanation:

Because the discount is 10% of the already discounted 30%

But when it is 40% you are taking the 40% of the Original price not of the already discounted price

The 40% would be cheaper

Example: Item 1 cost $10

40% of $10 is $4off

So it would cost $6

But 30%of $10 is $3 off

So it would be $7

Then you take 10% of $7 which would be 0.70 off

So in total it would cost $6.30

40% off would be cheaper

Sorry for being too wordy

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
