If anyone could help with this question here it would mean so much, I can't work out the answer. Could you also provide a explanation|?

Billy invests £800 for five years in a savings account. By the end of the five years he has received a total of £96 pound interest. Work out the annual rate of simple interest.

The rate is 2.4% per year.

Step-by-step explanation:

The basic formula is Dividend equals Principal times rate times time.

Time is usually the number of years

Dividend means the same as Interest, but we can use D instead if I which is confusing. So  D=Prt

Principal is the original amount invested or deposited

You are given D = 96, P = 800  t = 5

r is unknown, that's what you have to solve to find

Put the numbers into the formula:  96 = (800) × r × (5)

Divide:  96/(800)(5) =r  That's 96 ÷ 4000 = r  Calculate that to get 0.024 and change the decimal to a percent.

That means the rate of interest is 2.4%

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
