Maggie is considering two investments. Investment A Investment B Principal $10,000 $8,000 Interest rate 3% 2.8% Time in years 5
lana [24]
To solve this we are going to use the simple interest formula: A=P(a+rt)
where
A is the final amount.
P is the initial investment. 
r is the interest rate in decimal form.
t is the time in years. 

Investment A. We know that the initial investment is $10,000, so P=10000. We also know that the number of years is 5, so t=5. To convert the interest rate to decimal form, we are going to divide the rate by 100%
r= \frac{3}{100} =0.03
Lets replace those values in our formula to find A:
A=P(a+rt)
A=10000(1+0.03*5)
A=11500

Investment B. P=8000, t=15, and r= \frac{2.8}{100} =0.028.
A=P(a+rt)
A=8000(1+0.028*15)
A=11360

We can conclude that investment A will be worth than investment B at the end of the investment period.

What is the value of the x variable in the solution to the following system of equations? 3x + 2y = 8 2x + 3y = 2
malfutka [58]
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)

A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 11 feet. The width of
valentina_108 [34]

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)

irga5000 [103]
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
