Shani borrowed $5000 at an annual interest rate of 4% compounded yearly. William borrowed the same amount of money at an annual

Natalka [10]

Answer: William will pay $ 330.76 more interest than Shani at the end of 3 years.

Step-by-step explanation:

Compound interest = $P((1+r)^t-1)$ <em> , </em>P= principal , r= rate of interest , t= time

Given: P = $5000 , t= 3 years

For Shani , r= 4% = 0.04

Compound interest = $5000((1+0.04)^3-1)$

$=5000(1.124864-1)\\\\=5000(0.124864)\\\\=\$\ 624.32$

For William, r= 6%= 0.06

Compound interest = $5000((1+0.06)^3-1)$

$=5000(1.191016-1)\\\\=5000(0.191016)\\\\=\$\ 955.08$

Difference = $ ( 955.08- 624.32)

= $ 330.76

Hence, William will pay $ 330.76 more interest than Shani at the end of 3 years.

Solve5(2x-3) = 3(x+4)

balu736 [363]

$5(2x-3)=3(x+4) \\
10x-15=3x+12 \\
10x-3x=12+15 \\
7x=27 \\
x=\frac{27}{7}=3 \frac{6}{7}$
