tester [92]
So,

1st year: 3
2nd year: 4(first year), which is 12
3rd year: 6(first year), which is 18

The sum of the 1st, 2nd, and 3rd years is 3 + 12 + 18 = 33

Now, multiply 33 by the price at which Mr. Jackson sold each computer ($185).

We get $6105.  Mr. Jackson's gross profit was $6105.

what interest rate is needed to turn $2500 into $15,000 in 14 years if interest is compounded weekly?
Anastasy [175]

Answer:

0.6845% per week.

Step-by-step explanation:

Simple Interest Calculation A = P(1 + rt)

Solving our equation:

r = (1/730.5)((15000/2500) - 1) = 0.00684463

r = 0.00684463

Converting r decimal to R a percentage

R = 0.00684463 * 100 = 0.6845%/week

Calculating the annual rate

0.6845%/week × 52 weeks/year = 35.594%/year.

The interest rate required to get a total amount, principal plus interest, of $15,000.00 from simple interest on a principal of $2,500.00 over 14.05 years (730.5 weeks) is 0.6845% per week.
