Desiree put $175 into a cd that pays 6% interest compounded semiannually. according to the rule of 72, approximately how long will it take for her money to double? a. 16 years b. 12 years c. 8 years d. 18 years

12 yrs is the answer it will take to double her money

72/6=12

12 years - APEX

Step-by-step explanation:

Ok so there's 5 sides

let's find interior angle sum

formula is S=180(n-2)

n in this case is 5 since there are 5 sides

S=180(5-2)
S=180(3)
S=540

so now add the 5 angle lengths up to 540

5x+2+10x-3+7x-11+13x-31+8x-19=540
43x+-62=540
+62 +62
43x=602
divide both sides by 43
x=14
