Step-by-step explanation:

If his monthly salary is $2000 and 2% commission.

He made $30,000 in sales for the month so lets make an equation.

s = total salary

s = $2,000 + .02($30,000)

s = $2,000 + $600

s = $2600

Randy's salary for the month is $2600.

A farmer wishes to enclose a rectangular pasture with 1200 ft of fence. He needs to divide this rectangle into two smaller recta

Minchanka [31]

Answer: $60,000 ft^2$

Step-by-step explanation:

Given

total of 1200 ft of fence is available

Suppose rectangular pasture has following dimension as shown in figure.

total perimeter

$P=4a+3b$

$1200=4a+3b$

$4a=1200-3b$

$a=300-\frac{3}{4}b$

Area of rectangle is

$A=2a\times b$

$A=2(300-\frac{3}{4}b)b$

$A=2[300 b-\frac{3}{4}b^2]$

For maximum area, differentiate A w.r.t b

$\frac{\mathrm{d} A}{\mathrm{d} b}=300-\frac{3}{2}b=0$

$300=\frac{3}{2}b$

$b=200 ft$

so $a=300-150=150\ ft$

so area is

$A=2\times 150\times 200$

$A=60,000 ft^2$
