Answer:
FV= $8,436
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $5,700
Simple interest (i)= 8% = 0.08
Number of periods (n)= 6 years
<u>To calculate the future value (FV), we need to use the following formula:</u>
FV= PV*i*n + PV
FV= 5,700*0.08*6 + 5,700
FV= $8,436
The answer is A. Just remember the acronym for foil.
Answer:
C. 31.83 feet.
Step-by-step explanation:
We have been given that Trina has $1000 to purchase an open-top cylindrical dog pen in her backyard. She wants the height of the pen to be 5 feet.
First of all, we will find the surface area of dog pen using surface area of cylinder.
,where,
r = Radius of cylinder,
h = Height of cylinder.
Since the area of each square foot of pen costs $1, so in $1000 Trina can cover an area of 1000 square feet.
Now, we will set the surface area of cylinder equal to 1000 to solve for the radius.
Upon dividing both sides of our equation by 10 pi we will get,
Therefore, the radius of the dog pen is 31.83 feet and option C is the correct choice.

Answer:
1 toast costs $0.30 and 1 egg cost $0.60
Step-by-step explanation:
Let price of 1 egg be and price of 1 toast be
<u>"$1.50 for 2 eggs and one piece of toast":</u>
We can write
<u>"$.90 for one egg and one piece of toast":</u>
We can write
Now, we can solve the first equation for t and substitute that into 2nd equation and solve for e:
Now using the value of e (0.6) and putting it back in the first equation, we will get t:
Hence, 1 toast costs $0.30 and 1 egg cost $0.60
