The annual interest rate is 6.2%.
Solution:
Given data:
Interest = $310
Principle = $1000
Time = 5 years
To find the annual interest rate:
<u>Simple Interest formula:</u>
Substitute the given values in the formula, we get
Do cross multiplication.
Divide both sides of the equation by 1000, we get
Divide by 5 on both sides of the equation, we get
R = 6.2%
Hence the annual interest rate is 6.2%.
we conclude that at 5:00 p.m. there are 8 more inches of snow than at 8:00 a.m.
<h3>How many more inches of snow were on the ground at 5:00 p.m. than at 8:00 a.m.?</h3>
We know that at 8:00 a.m. there were t inches of snow in the ground.
At 5:00 p.m. there were 3t inches of snow in the ground.
Then the difference between the heights of the snow is:
3t- t = 2t
And we know that at 5:00 p.m. there were 12 inches of snow then we can solve the linear equation for t:
3t = 12in
t = (12in)/3 = 4 in
Replacing that in the difference of heights:
2t = 2*4in = 8in
From this, we conclude that at 5:00 p.m. there are 8 more inches of snow than at 8:00 a.m.
