18= (d - 0.25d) - 0.25d
18= 0.75d - 0.25d
18= 0.50d
d = 36
the original price was $36

Answer:
y = 14 
Step-by-step explanation:
For an exponential function of the form y = a
Use the given points to find a and b
Using (0, 14 ), then
14 = a (
 (  = 1 ) , thus
 = 1 ) , thus
a = 14
y = 14
Using (3, 3024 ) , then
3024 = 14 b³ ( divide both sides by 14 )
216 = b³ ( take the cube root of both sides )
b = ![\sqrt[3]{216}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B216%7D) = 6 , thus
 = 6 , thus
y = 14 ×  ← exponential function
 ← exponential function
