Apillow that usually costs $18 is marked down 25%. which expressions can be used to find the new price of the pillow? check all that apply. 18 – 0.25(18) 18 – 0.75(18) 0.25(18) 0.75(18) 18(0.25) + 18

In this case we can propose a rule of three:

$ 18 ---------------> 100%

x --------------------> 25%

Where x represents the discount made to the pillow:

So we have the new price (with the discount) is:

In addition, if 25% is discounted we have to, the price of the pillow is 75% of the original price. That is to say:

Option A

Option D

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
