If the item is 30% off, the new price is 0.7p because we want to know how much 70% of the original price was.
Answer:
Negative
Step-by-step explanation:
Positive discriminant: graph cuts x axis twice
Zero discriminant: graph touches x axis once
Negative discriminant: graph does not cut or touch x axis
Her mistake is that she did the change in x over the change in y. It should be the change in y over the change in x. So: -2-3/-2-4
12/20=.6
Thus, move the decimal point two places to the right, and the answer is 60%
Siamone has $65.32 + DAN
Dan has CARLY - $37.50
CARLY = $127.75
Plug Carly into Dan's equation...
$127.75 - $37.50 = $90.20
DAN = $90.20
Plug Dan into Siamone's equation
$65.32 + $90.20 = $155.57
