How much money will be in a bank account after 4 years if $8 is deposited at an interest rate of 5%?
stealth61 [152]

Answer:

$9.60

Step-by-step explanation:

The question above is a simple interest question.

The formula for the amount of money after a given period of time using simple interest is given as:

A = P(1 + rt)

Where

P = Initial Amount saved or invested = $8

R = Interest rate = 5%

t = Time in years = 4

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year.

Solving our equation:

A = 8(1 + (0.05 × 4)) = 9.6

A = $9.60

The amount of money that will be in a bank account after 4 years is $9.60

Write an expression for the model. Find the sum. options: a) 2 + (–3); 1 b) –3 + 2; 5 c) 2 + 3; 5 d) 2 + (–3); –1
Dima020 [189]

Answer:

c) 2 + 3 = 5                   TRUE

d) 2 + (–3) = -1              True

Step-by-step explanation:

When adding integers (positive and negative whole numbers), there are three cases:

  • Positive and positive increases and sum is positive. Ex. 4 + 6 = 10
  • Positive and negative where you subtract and take the sign of the larger number. Ex. 3 + -8 = -5 or -3 + 8 = 5
  • Negative and negative decrease and the sum if negative. Ex. -4 + -6 = -10.

Use these rules to simplify each expression.

a) 2 + (–3) = -1 not 1     FALSE

b) –3 + 2 = -1 not 5      FALSE

c) 2 + 3 = 5                   TRUE

d) 2 + (–3) = -1              True

Brums [2.3K]

Answer:

<u>Yes</u>

Step-by-step explanation:

<u>When there are 2 rows</u>

  • Number of erasers per row =  No. of erasers / No. of rows
  • Number of erasers per row = 18/2
  • Number of erasers per row = 9

<u>When there are 3 rows</u>

  • Number of erasers per row =  No. of erasers / No. of rows
  • Number of erasers per row = 18/3
  • Number of erasers per row = 6

<u>Therefore, there will be more erasers per row in 2 equal rows than in 3 equal rows.</u>

Solve x = 0.6x + 384
Gelneren [198K]
X = 0.6x + 384        |subtract 0.6x from both sides

0.4x = 384    |divide both sides by 0.4

x = 960
