For continuously compounded interest:
Amount = Principle * e^(rate * time)
A rate of 8% converted to a decimal value: r=0.08
With time t=4
and amount 1190
Plug all these values in,
1190 = Principle * e^(0.08 * 4)
And use your calculator to solve for the principle.
Maybe we'll call it P to make things easier.
1190 = P * e^(0.08 * 4)
1190 = P * 1.377
The principle is being multiplied by this 1.377,
divide by 1.377 to undo the multiplication.
864.11735 = P
Answer:
The cost of tuition fee after 4 years is $15,149.72.
Step-by-step explanation:
Exponential function:
A= the amount after n years
P= Initial amount
r= rate of increasing
n= time in years
The cost of tuition at a college is $12,000. It is increasing at the rate of 6% each year.
Here, P= $12,000, r= 6%= 0.06, n= 4 years.
=$15,149.72
The cost of tuition fee after 4 years is $15,149.72.
Answer:
3/10
Step-by-step explanation:
multiply 10k to 0.3125 and you get 3,125 but if you put it in decimal form its 3.125 (3,125 ÷ 10,000) you can round down to 3 since the numbers on the right side of the decimal does not go over 5. (Simplist Form)
48/1 x 3/8 = 144/8 = 18
OR
Divide 48 in 8 parts and then take 3 of those
48/8=6
6x3=18
Answer:
80%
Step-by-step explanation:
16/20×100
0.8×100=80
