Lori buys a $459 certificate of deposit (CD) that earns 5.6% interest that compounds monthly.

Compound interest formula is

P = principal amount  

r  = annual rate of interest  

t  = number of years  

A = amount of money  after n years, including interest.  

n  =  number of times the interest is compounded per year  

Given P = 459

r= 5.6% = 0.056

t = 6

compounded monthly means n = 12

Plug in all the values in the formula

A= 456* 1.3982456

A= 637.60

CD will be $637.60 worth in 6 years

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
