Answer:
D
Step-by-step explanation:
SOO SORRY I EDITED THIS BC A WAS WRONG I MISREAD
if 24 cards = $12, 1 card = $2 (24 / 12)
dozen = 12
if half of 24 is 12, and 24 cards cost $12, half of 12 is 6. same goes for the price. $12 / 2 = 6.
-2/3 < y < 0
y = Asin(x)
Edit*
There's a node (y=0) at pi for sine wave. At 3/2pi will be the min. So range goes from -2/3 to 0
l=41.5
Using the formula A=wl
l= ==41.5
A is the answer to your problem
Answer: 48-240+300x
