Let Tamara invests amount X in 3% account. She invests 8000-X in 2% account.

The interest after t years is given by

I=Prt. After 1 year the two interests are equal, that is

X(\frac{3}{100}) (1)=(8000-X)(\frac{2}{100}) (1)\\ 3X=2(8000-X)\\ 5X=16000\\ X=3200

Thus, Tamara has to invest \$3200 in 3% account and \$8000-\$3200=\$4800 in 2% account.

A rancher has 140 feet of fence with which to enclose three sides of a rectangular garden (the fourth side is a cliff wall and w
Scilla [17]
A rancher wants to enclose a rectangular field with 220 ft of fencing.
One side is a river and will not require a fence.
What is the maximum area that can be enclosed?
:
The field requires only 3 sides of fence, therefore
L + 2W = 220
L = (220-2W); we can use this for substitution in the Area equation
:
Area
A = L*W
replace L with (220-2W)
A = W(220-2W)
A = -2W^2 + 220W
A quadratic equation, max A occurs at the axis of symmetry, x = -b/(2a)
In this equation
W = %28-220%29%2F%282%2A-2%29
W = 55 ft is the width for max area
:
Find the max area
A = -2(55^2) + 220(55)
A = -2(3025) + 12100
A = 6050 sq/ft is the max area
:
:
Confirm this with the dimensions calculated; 110 * 55 = 6050
