Answer: B. 
Step-by-step explanation:
The formula to find the compound amount (compounded yearly):-
, where P is the principal amount invested, is the rate of interest and t is time period.
As per given , we have
P=$5500 , r=5% = 0.05 and A = $7,739.05.
Substitute all the values in the formula , we get
Hence, the equation describes Meredith's investment based on t, the number of years she kept the account open :
Answer:
For the question about sea tempuratures: 48. For the image, from top to bottom, 8, -14, -13, and 13.
In 8 years both salaries will be the same
28+3x=36+2x
since we want to see when they will be the same we set them equal to each other, first subtract 28 and what you do on one side you have to do to the other so subtract 28 from 36 aswell, then you'll get 3x=8+2x so subtract 2x from both sides to get x=8 then thats your answer

Answer:
9 weeks
Step-by-step explanation:
In problems of this nature, the usual assumption is that the time required is proportional to the work product and inversely proportional to the number of people doing the job. Here, there is no change in the amount of work, but the number of people is reduced by a factor of 12/18 = 2/3.
So, the amount of time required is expected to increase by a factor of 1/(2/3) = 3/2.
(6 weeks)×(3/2) = 9 weeks
It would have taken 9 weeks to sew the 540 dresses.
