Answer:
<h3>$4,789.99</h3>
Step-by-step explanation:
Using the formula for calculating the compound interest
A = P(1+r)^t
P is the principal = $3500
r is the rate = 4% = 0.04
T is the time = 8 years
Substitute
A = 3500(1+0.04)^8
A = 3500(1.04)^8
A = 3500(1.3686)
A = 4,789.99
Hence the resulting balance is $4,789.99
Marcia dissolved 1 kg of salt in 3 litres of water
Bobby dissolved 2 pounds of salt in 7 pints of water
We know that
1 litre = 2.11 pints
We also know that
1 pound = 0.4535 kg
Now if we take the case of Bobby, and convert the pound to
kg then
1 pound = 0.4535 kg
2 pounds = (0.4535 * 2) kg
<span> =
0.907 kg</span>
<span>
= 0.91
kg</span>
Bobby dissolved the salt in 7 pints of water
We know
2.11 pints = 1 litre
Then
7 pints = (7/2.11) litre
<span> = 3.32
litres</span>
So we now see that Bobby has dissolved 0.91 kg of salt in
3.32 litres of water
Marcia dissolved 1 kg of salt in 3 litres of water.
So Marcia has made a more concentrated solution since she
has dissolved more salt in less amount of water whereas Bobby has dissolved
less amount of salt in more water.
When 36 is decreased by 75%, the result is 9.
75% of 36 is 27.
36 - 27 = 9
Answer:
B
