Options
(0, 35)
(10, 30)
(15, 25)
(20, 15)
Answer:
(C) (15,25)
Step-by-step explanation:
The profit p in dollars of selling x widgets and y gadgets is given by the function p(x,y)=7x+6y.
Option A
When x=0 and y=35
p(x,y)=7(0)+6(35)
p(x,y)=210
Option B
When x=10 and y=30
p(x,y)=7(10)+6(30)
p(x,y)=250
Option C
When x=15 and y=25
p(x,y)=7(15)+6(25)
p(x,y)=$255
Option D
When x=20 and y=15
p(x,y)=7(20)+6(15)
p(x,y)=$230
We observe that the point (15, 25) in Option C yields the highest profit ($255). Therefore, it is the point that maximizes profit.
The cost is 24 cents per foot.
We find this by dividing the cost of the roll by the number of feet in the roll:
47.03/200 = 0.235 ≈ 0.24
Answer:
n = 5.5
Step-by-step explanation:
4n - 10 = 12
4n = 12 + 10
4n = 22
n = 22/4
n = 5.5
Answer:
The total investment is $5020.19
Step-by-step explanation:
Given : $2150 invested at 5.3% for 16 years and compounded continuously
To find : What is the total investment?
Solution :
The formula of continuously compounded interest is
Where A = amount invested
P = principal = $2150
e = Euler's number (on calculator)
r = interest rate as decimal = 5.3%=0.053
t = time in years = 16 years
Substitute the value in the formula,
Therefore, Option 4 is correct.
The total investment is $5020.19.
