Answer:
30 cents
Step-by-step explanation:
Before the sale 9 candy bars would be .2 x 9 = $1.80. 9 candy bars on the sale would be 9 divided by 3 times .5 which is $1.50. So the savings is 1.80 - 1.50 = .30 or 30 cents.
Answer:
b = 
Step-by-step explanation:
Given
a = 
bh
Multiply both sides by 2 to clear the fraction
2a = bh ( divide both sides by h )
= b
The area is:
A = x * y = 20000
The cost function is:
C = 2.50 (2x) +3.50 (2y)
Rewriting we have:
C = 5x + 7y
Writing as a function of x we have:
C = 5x + 7 (20000 / x)
Rewriting:
C (x) = 5x + 140000 / x
We derive:
C '(x) = 5-140000 / x ^ 2
We equal zero and clear x:
0 = 5-140000 / x ^ 2
140000 / x ^ 2 = 5
x ^ 2 = 140000/5
x = root (140000/5)
x = 167.33 feet
Therefore the cost is:
C (167.33) = 5 * (167.33) + 7 * (20000 / 167.33)
C (167.33) = 1673.32 $
Answer:
