Write an equation to determine the selling price in dollars, , on an item that is originally priced dollars after a
markdown of 15%.

X = original cost

Y = Marked down cost

0.85x = y

Here's why:

When multiplying by percentages, what you multiply by is what is left over so 0.15x is incorrect because that would mean you marked it down by 85%!

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^

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
