Answer:

Cost of travel insurance for 4 days = 19 pounds

Step-by-step explanation:

The insurance company uses the formula T = 3.5n + 5 to work out the cost , T pounds for  insuring the customer for n number of days . Where n is the number of days.

The algebraic equation given has two variables which are cost T of insuring and n which is the number of days for insuring. Mathematically,

T = cost of insuring in pounds

n = number of days

Therefore, finding the cost T for 4 days

T = 3.5n + 5

T = 3.5 × 4 + 5

T = 14 + 5

T = 19 pounds

Cost of travel insurance for 4 days = 19 pounds

Sam invests $800 at 6%/a compounded annually for 5 years. What is the total interest<br> earned?
s2008m [1.1K]
<h3>Answer:    270.58 dollars</h3>

======================================================

Work Shown:

  • A = account value after t years
  • P = principal or amount deposited = 800
  • r = interest rate in decimal form = 0.06
  • n = number of times we compound per year = 1
  • t = number of years = 5

So,

A = P*(1+r/n)^(n*t)

A = 800*(1+0.06/1)^(1*5)

A = 1070.58046208

A = 1070.58

After five years, the account will have $1,070.58 in it.

The amount of interest earned is A-P = 1070.58 - 800 = 270.58 dollars.
