Answer:

27, 28, 29 and 30

Step-by-step explanation:

Let the integers be:

n, n + 1, n + 2 and n + 3

Their sum is 114:

n + n + 1 + n + 2 + n + 3 = 114

Solving for n:

4n + 6 = 114
4n = 108
n = 108/4
n = 27

The numbers are: 27, 28, 29 and 30

Austin borrowed money from a credit union for 4 years and was charged simple interest at an annual rate of 5% the total interest

Reika [66]

Given:

Rate of simple interest = 5%

Time = 4 years

Total interest = $160

To find:

The amount borrowed by Austin from a credit union.

Solution:

The formula for simple interest is:

$I=\dfrac{P\times r\times t}{100}$

Where, P is principal, r is the rate of interest and t is the number of years.

Putting $I=160,r=5,t=4$ in the above formula, we get

$160=\dfrac{P\times 5\times 4}{100}$

$160=\dfrac{20P}{100}$

$160=\dfrac{P}{5}$

Multiply both sides by 5.

$800=P$

Therefore, Austin borrowed $800 from a credit union for 4 years.
