15 = 0.25x
1500 = 25x
60 = x
The original price was $60.
Answer:
Step-by-step explanation:
y= a*b x (a is initial value b = growth rate) y= 8000(-1)^1 x= 1.018^1 x 1.8
x = 0.1527 = time x 12.
f(x)=x. f ( x ) = x . = 0.1527 x 12
or we can square so that x^2 = 1.8 and x = 1.34164 note this can only be used for the first 5 decimal place.
This shows the exponential growth we expand and introduce y = 8000(-1)^12 to find one year.
One year y-1^12 this represents 144 the 1.8% of the y = 144 the starting point of 1/12 on axis.
f(x)=2x. f ( x ) = 2x add y (1)^1 would show year 2 at the same rate,
11a:
3x+5=5x-57
3x-5x=-57-5
-2x=-62
x=31
11b:
2x+2x+4x+150+4x+150=360
12x+300=360
12x=360-300
12x=60
x=5
hope this helped !!
