the cost of 6 sandwhiches and 4 drinks is $53. the cost of 4 sandwhiches and 6 drinks is $47. how much does one sandwhich cost
Blizzard [7]

6s+4d=$53

4s+6d=$47

Multiply 6 in the first equation which is

36s+24d=$318

Multiply -4 in the second equation which is

-16s-24d=$-188

Then..

36s+24d=$318

-16s-24d=$-188

You cancel out the -24d and +24d

36s=$318

-16s=$-188

Do the math..

20s=$130

Divide 20 by both sides and answer...

s=$6.5

walnut grower estimates from past records that if 20 trees are planted per acre, then each tree will average 60 pounds of nuts p
laila [671]

Answer:

5 trees should be planted to maximize the yield per acre,

The maximum yield would be 1250

Step-by-step explanation:

Given,

The original number of trees per acre = 20,

Average pounds of nuts by a tree = 60,

Let x be the times of increment in number of trees,

So, the new number of trees planted per acre = 20 + x

∵ for each additional tree planted per acre, the average yield per tree drops 2 pounds,

So, the new number of pounds of nut = (60 - 2x)

Thus, the total yield per acre,

Y(x) = (20+x)(60-2x)

Differentiating with respect to t ( time ),

Y'(x) = (20+x)(-2) + 60 - 2x = -40 - 2x + 60 - 2x = 20 - 4x

Again differentiating with respect to t,

Y''(x) = -4

For maxima or minima,

Y'(x) = 0

⇒ 20 - 4x = 0

⇒ 20 = 4x

⇒ x = 5,

For x = 5, Y''(x) = negative,

Hence, Y(x) is maximum for x = 5,

And, maximum value of Y(x) = (20+5)(60 - 10) = 25(50) = 1250,

i.e. 5 trees should be planted to maximize the yield per acre,

and the maximum yield would be 1250 pounds
