Hi!
To solve this question you need to solve 7^8 x 6
7^8 = 5,764,801
5,764,801 x 6 = 34,588,806
The equation relating length to width
L = 3W
The inequality stating the boundaries of the perimeter
LW <= 112
When you plug in what L equals in the first equation into the second equation, you get
3W * W <= 112
evaluate
3W^2 <= 112
3W <=

W <=

cm
Answer:
1800 dollars
Step-by-step explanation:
We can set up an equation here to represent the exponential growth in Terry's bank account.

We can plug in 3 for x since x is the # of years the account is receiving compound interest on.


I = Prt
Interest on CD = 0.0425 x $1,800 = $76.5
Interest on savings = 0.0275 x $1,800 = $49.5
Difference of interest on CD and Interest on savings = $76.5 - $49.5 = $27
Therefre, he will earn $27 more if he invest in a CD rather than in a savings.
