Shandra's parents put $1,500 in her bank account for college tuition. At an interest rate
gavmur [86]

Answer:

$6,427.99

Step-by-step explanation:

-We first find the effective annual interest rate as follows:

i_m=(1+i/m)^m-1\\\\=(1+0.0825/2)^2-1\\\\=0.084202

#We the use this rate to find the compounded amount after 18 years:

A=P(1+i_m)^n\\\\=1500(1.084202)^{18}\\\\=6427.99

Hence, the amount after 18 years is $6,427.99

Amir pits £3035 into a bank account. The account pays 4% compound interest each year. Work out how much money amir will have in
myrzilka [38]

Answer:

\£3840.2

Step-by-step explanation:

Let P denotes principal amount, T denotes time period and R denotes rate of interest.

Amount = P(1+\frac{R}{100})^T

Amir pits £3035 into a bank account. The account pays 4% compound interest each year.

Put P=\£3035,\,R=4\%,\,T=6

Amount = 3035(1+\frac{4}{100})^6=3035(\frac{104}{100})^6=\£3840.2

Therefore, Amir will have \£3840.2 in the account after 6 years.

The square footage and monthly rental of 10 similar one-bedroom apartments yield the linear regression
Triss [41]

The footage of the room with a rental price of $1500 is 709 square foot

<h3>Linear equation</h3>

A linear equation is given by:

  • y = mx + b

where m is the rate of change, b is the initial value of y, y, x are variables.

Let y represent the monthly rental price and x represent the square footage. Given the equation:

y = 0.7752x + 950.25

For a rent of $1500:

1500 = 0.7752x + 950.25

  • x = 709 square foot.

The footage of the room with a rental price of $1500 is 709 square foot
