Answer Interest rate = 12.3%
The compound interest formula is given by:
Where
A = Future amount
P = Present amount (Principal amount)
r = Interest rate in decimal form
n = No. of times compounded per year
t = time in years.
We can say that if:
Present amount = P
Future amount = 3P
r = 12.3/100 = 0.123
n = 1
t = ?
Substitute the values in the formula of compound interest:
Taking log on both sides.
Round off to nearest option
t ≅ 9 years
3.66666666 but u can round it to the third place
0x+2 =y
So technically x+2=y
6/10= 3/5
Or 6/10=6/10
Or 6/10= .6
Answer:
$79.04
Step-by-step explanation:
First you have to figure out how much the discount would be.
123.50 X .36 = 44.46
Then all you have to is subtract that from the original cost
123.50 - 44.46 = 79. 04
