Answer:

get 1 … what? free? half-price? something else?

Let x= price of 1 item

Then 3x= price of 3 items

Buy 2 , get 1 free

Total cost =2x

Discount =3x−2x=x

Discount percentage =x/(3x)=0.333…=3313%

Buy 2 , get 1 half price

Total cost =2x+0.5x=2.5x

Discount =3x−2.5x=0.5x

Discount percentage =0.5x/(3x)=0.1666…=1623%

The height of a stack of DVD cases is proportional to the number of cases in the stack. The height of 6 DVD cases is 114 mm.

Zanzabum

OK so my answer is from what you’ve just explained that means you multiply the six and the 114 is 684 so that means if you have to do that to 13 of them that means 684×13 is what your equation would be in the answer to 684×13 is 8892

Let length be x

Width be 2x

ATQ

$\\ \sf\longmapsto 2(L+B)=24$

$\\ \sf\longmapsto 2(x+2x)=2=$

$\\ \sf\longmapsto 2(3x)=24$

$\\ \sf\longmapsto 6x=24$

$\\ \sf\longmapsto x=\dfrac{24}{6}$

$\\ \sf\longmapsto x=4$
