1000 was invested at 5.5% interest, compounded annually. After sometime the amount had grown to 1550. How long was the money inv

scZoUnD [109]

compound interest equation for annually compounded

$A=P(1+r)^t$

A=final amount

P=principal

r=rate in decimal

t=time in years

given that

A=1550

P=1000

r=5.5%=0.055

find t

$1550=1000(1+0.055)^t$

divide both sides by 1000

$1.55=1.055^t$

take ln of both sides

$ln(1.55)=ln(1.055^t)$

use ln rule $ln(a^b)=b(ln(a))$

$ln(1.55)=t(ln(1.055))$

divide both sides by ln(1.055)

$\frac{ln(1.55)}{ln(1.055)}=t$

using a calculator, we get that t=8.18544 yrs

so about 8.2yrs

Vilka [71]

Answer:

Annie can make 4 plates with $8:4=2$ apples and $20:4=5$ apricots on each plate.

Step-by-step explanation:

Annie has 8 apples and 20 apricots.

Factor these numbers:

$8=2\cdot 4=2\cdot 2\cdot 2\\ \\20=2\cdot 10=2\cdot 2\cdot 5$

Find GCF(8,20):

$GCF(8,20)=2\cdot 2=4$

Hence, Annie can make 4 plates with $8:4=2$ apples and $20:4=5$ apricots on each plate.
