Answer:
QII
Step-by-step explanation:
I'm thinking that this is supposed to be a quadratic and you forgot the ^2 at the end of the (x + 3). IF this is the case, then the vertex form of a quadratic is
where the h inside the parenthesis with the x- indicates side to side movement and the k indicates up and down movement. Both translations begin at the origin, of course. The important thing to remember here is that the form "x -" is constant. So if our quadratic reflects "x - 3", then it is understood to be "x - (3)" and the movement is 3 units to the right. If the quadratic reflects "x + 3", then it is understood to be "x - (-3)" and the movement is 3 units to the left. Our quadratic, then, is shifted 3 units to the left of the origin and up 2 units, putting us in QII.
If this is what it appears to be, (x + 3) + 2, then it is x + 5 which is a line that has no vertex (which is why I'm thinking it must be a mistyped quadratic!)
STEP 1:
Discount $= Price times discount %
=$5.00 * 50%
=$5.00 * 0.50
=$2.50 discount amount
STEP 2:
Sale price= Original $ - Discount amount
=$5.00 - $2.50
=$2.50 sale price
ANSWER: Discount amount is $2.50 and the sale price is also $2.50.
Hope this helps! :)
