Kremena's bank account earns 4.5% simple interest per year. How much must she deposit in the account today if she wants it to be worth $1,250 in 3 years? Round your answer to the nearest dollar.

Answers

Answer 1

Answer:

Answer: $1101 must be deposited into the account.

Step-by-step explanation:

Let x represent the amount that must be deposited.

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents the interest after T years.

P represents the principal or initial amount deposited.

T represents the amount of time for which the money is left in the account in years.

R represents the interest rate.

From the information given,

P = $x

T = 3 years

R = 4.5%

I = 1250 - x

Therefore,

1250 - x = (x × 4.5 × 3)/100

1250 - x = 0.135x

x + 0.135x = 1250

1.135x = 1250

x = 1250/1.135

x = 1101 to the nearest dollar

Answer 2

Answer:

Answer:

1095$ should be invested today .

Step-by-step explanation:

The formula of present value will be applied here :

Present Value= Future Value/(1+ interest rate)^Years

Present Value = 1250/(1.045)^3

The width of a picture frame is x inches and the length is x+3 inches, what is the value of x if the area must be 40 square inches

Answers

Answer:

x = 5

Step-by-step explanation:

Width = x inches

Length = (x+3) inches

Area = 40 sq inches

The area of a rectangular shaped object is given by :

$A=l* b$

Putting all the values,

$x(x+3)=40\n\nx^2+3x-40=0\n\nx^2+8x-5x-40=0\n\nx(x+8)-5(x+8)=0\n\n(x-5)(x+8)=0\n\nx=5,-8$

Neglecting x = -8.

So, the value of x is 5.

It's was 55°F outside until the temperature increased 20°F. Which number is the additive inverse of the temperature increase? A) −20 B) −55 C) 20 D) 55

Answers

Answer:

Option A) -20°F.

Step-by-step explanation:

Given : It's was 55°F outside until the temperature increased 20°F.

To find : Which number is the additive inverse of the temperature increase?

Solution :

Additive inverse is defined as,

For any number 'a', the additive inverse is $a+(-a)=0$ or $-1\cdot a=-a$

According to question,

The temperature is increased 20°F.

To follow the additive inverse property,

The sum became zero.

So, Additive inverse is -20°F.

Therefore, Option A is correct.

The additive inverse of the temperature increase is -20°F.

A) -20

A small toy car costs $3 a large toy car cost 5 times as much as the small one.

Answers

Answer:

$15

Step-by-step explanation:

Good Morning!

If the small toy car costs $3.00, and the large toy car costs 5 times as much as the small one, we can multiply the value of the small car by five to find the value of the large car.

Since five times 3 = 15, the value of the large toy car is $15.00.
