Answer:
d. r/12 = 3
Step-by-step explanation:
r = 3(12)
r/12 = 3
To solve this we are going to use the simple interest formula:

where

is the final amount.

is the initial investment.

is the interest rate in decimal form.

is the time in years.
Investment A. We know that the initial investment is $10,000, so

. We also know that the number of years is 5, so

. To convert the interest rate to decimal form, we are going to divide the rate by 100%

Lets replace those values in our formula to find

:


Investment B. 
,

, and

.



We can conclude that
investment A will be worth than investment B at the end of the investment period.
Solve your system of equations.
3x+2y=8;2x+3y=2
Solve 3x+2y=8 for x:
3x+2y+−2y=8+−2y(Add -2y to both sides)
3x=−2y+8
3x/3=−2y+83(Divide both sides by 3)
x=−2/3y+8/3
Substitute (−2/3y+8/3) for x in 2x+3y=2:
2x+3y=2
2(−2/3y+8/3)+3y=2
5/3y+16/3=2(Simplify both sides of the equation)
5/3y+16/3+−16/3=2+−16/3(Add (-16)/3 to both sides)
5/3y=−10/3
5/3y5/3=−10/35/3(Divide both sides by 5/3)
y=−2
Substitute (−2) for y in x=−2/3y+8/3:
x=−23y+83
x=−23(−2)+83
x=4(Simplify both sides of the equation)
Answer is A)
Answer:
A = x(x − 4) − 0.5(8)(x − 4) − 3(7)
Step-by-step explanation:
x = length, making the width (x-4)
The stage closet will be (x-4)(8)(1/2)
The rectangle is 7(3)
That makes the painted area x(x-4) - 4(x-4)
So...
A = x(x − 4) − 0.5(8)(x − 4) − 3(7)
Oranges
2(3.50) = 7.00
apples
4(3.25) = 13.00
carrots
2(1.90) = 3.80
potatoes
1(1.20) = 1.20
7 + 13 + 3.80 + 1.20 = 25.00 * .05 = 1.25
$25.00 - 1.25 = $23.75
