Answer: the resale value would be $791 after 4 years
Step-by-step explanation:
We would apply the formula for exponential decay which is expressed as
y = b(1 - r)^x
Where
y represents the value of the laptop computer after x years.
x represents the number of years.
b represents the initial value of the laptop computer.
r represents rate of decay.
From the information given,
P = $2500
x = 4
r = 25% = 25/100 = 0.25
Therefore,
y = 2500(1 - 0.25)^4
y = 2500(0.75)^4
y = $791
Well it depends on what the model is but if it's an IRA or whatever so if you make your own model that's easy
Whatever% of anything, is just (whatever/100) * anything.
the syrup is going to be 5lbs total, that includes the sugar in it as well as the water mix.
keeping in mind that the syrup will be a 1.5% syrup, namely 1.5% of it will be sugar, the rest just water then, how much is 1.5% of 5?
well, is just(1.5/100) * 5 or 0.075, namely lbs.
so, 0.075 lbs will be sugar and the rest water, the rest will be 5 - 0.075, or 4.925 lbs.
I think its D if not A hope this is helpful
-7/4:-1.75
2/5:0.4
-1.75=0.4t
-1.75/0.4=t
-4.375=t
Hope I helped you well, have a victorious day!
