An item is regularly priced at $25. Susan bought it on sale for 55% off the regular price.

$11.25

Step-by-step explanation:

Given that item is $25 before sale, susan bought for 55% off the regular price.

55% off $25 implies subtract 55% from $25

=55/100 × 25 = $13.75

Susan therefore bought the item at $25 - $13.75 = $11.25.

I hope this helps.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
