Answer:
28 - 8= 20 ÷ 5 = 4
Step-by-step explanation:
Use distributive property. The answer is 4
Answer:
-3 X 7= -21
Step-by-step explanation:
This is exponential decay which can be expressed as:
y=ab^t, y=final value, a=initial value, b=rate, t=time
In this case a=25000, r=(100-20)/100=0.8 so
y=25000(0.8^t), so in 4.5 years...
y=25000(0.8^4.5)
y≈$9158.93 (to nearest cent)
3.59999
or 3.6
hopefully this helps you!
