Using compound interest, it is found that they must deposit $9,143.47 in order to have the desired amount.
<h3>What is compound interest?</h3>
The amount of money earned, in compound interest, after t years, is given by:
In which:
- A(t) is the amount of money after t years.
- P is the principal(the initial sum of money).
- r is the interest rate(as a decimal value).
- n is the number of times that interest is compounded per year.
For this problem, the parameters are:
A(15) = 30000, r = 0.08, n = 4
Then we solve for P to find the initial deposit:
P = $9,143.47.

B. A,C, and D all simplify to 5, 12, 13 which is a pythagorean triple
Equation:
distance + distance = 2250 miles
3x + 3(x-110) = 2250
6x - 330 = 2250
6x = 2580
x = 430 mph (rate of the westbound plane)
x-110 = 320 mph (rate of the eastbound plane)

Answer:
$55.55
Step-by-step explanation:
To find the cost of the purchase add 4 times the cost of one large sack to the cost of one small sack:
4($11.55) +($9.35) = $46.20 + 9.35 = $55.55
The cost of 4 large sacks and 1 small sack would be $55.55.
