Answer:
The total earned money over the 5 year period=$14,000
Step-by-step explanation:
We are given that
Principle amount, P=$10000
Rate of interest, r=8%
Time, t=5 years
We have to find the total earned money over the 5 year period.
We know that
Simple interest=
Using the formula
S.I=[tex]\frac{10000\times 8\times 5}{100}{/tex]
S.I=$4000
Now,
Amount=P+S.I
Amount=10000+4000
Amount=$14000
Hence, the total earned money over the 5 year period=$14000
7x+y-9=0
move constant to the left by adding its opposite to both sides. the sum of the two =0
Answer:
The sum of two numbers is 18.
5 times the first number subtracted from 4/7 of the second number is 14.
First number --> x
Second number --> y
so
x + y = 18 --> x = 18-y
5x - (4/7)y = 14
so
5 (18-y) - (4/7)y = 14
90 - 5y - 4/7 y = 14
-5.57 y = 14-90
y = 13.64
so
x = 18 - 13.64
x = 4.36
Answer: 2years, 5 months
Step-by-step explanation:
Principal, P = $6000
Rate, R = 3%
Interest, I = $450
Time, T =?
Simple Interest, I = P x T x R/ 100
making T, subject of formula
T = 100 x I/ P x T
Substituting the values into the equation,
T = 100 x 450/ 6000 x 3
T = 45000/ 18000
T = 2.5years = 2years, 5 months
