Jameel alharbi deposited $1,500 in a savings account that earns 5% compounded quarterly. he made no other deposits or withdrawals. what is the amount in the account at the end of the second quarter?

$2562.87

$1537.73

$2050.31

$1025.00

The amount in the account at the end of the 2nd quarter is $1537.73 ⇒ 2nd answer

Step-by-step explanation:

* Lets revise the compound interest

- Compound interest can be calculated using the formula

 A = P (1 + r/n)^(nt)

Where:

•A = the future value of the investment, including interest

•P = the principal investment amount (the initial amount)

•r = the annual interest rate (decimal)

•n = the number of times that interest is compounded per unit t

•t = the time the money is invested for

* Now lets solve the problem

# P = $1500

# r = 5/100 = 0.05

# n = 4 ⇒ quarterly compound

# t = 1/2 ⇒ two quarters means 1/2 year

∴ A = 1500(1 + 0.05/4)^(4 × 1/2) = $1537.73

* The amount in the account at the end of the 2nd quarter is $1537.73

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
