Answer:
$189.75
Step-by-step explanation:
Whenever you want to find the percent of something, you need to turn the percent into a decimal. In this case, we need to find 115% of the wholesale price because there is a markup, so the cost will be higher.
115% as a decimal is 1.15. Here is how the equation will be set up:
$165 • 1.15 = $189.75
No rounding is necessary for this problem because it is already to the nearest cent.
The linear equation that models the value of the investment in the year x is y = 574x + 2700
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let y be the value of the investment in the year x, where x = 0 represents 1992
An investment is worth $2700 in 1992 (x = 0). By 1997 (x = 5) it has grown to $5570, hence:
y - 2700 = [(5570 - 2700)/(5 - 0)](x - 0)
y = 574x + 2700
The linear equation that models the value of the investment in the year x is y = 574x + 2700

Answer:
x = 600 m
y = 1200 m
Amax = 720000 m²
Step-by-step explanation:
Let call x the smaller side of the rectangular plot and y the largest ( we assume we have one y side bounded by a river: Then
A(p) Area of the plot x*y
A(p) = x*y
And perimeter of the plot ( to be fenced ) is:
P(p) = 2*x + y = 2400 ⇒ y = 2400 - 2*x
Area of rectangular plot as function of x:
A(x) = x * ( 2400 - 2x )
Taking derivatives on both sides of the equation
A´(x) = ( 2400 - 2x ) + (-2) *x ⇒ A´(x) = ( 2400 - 2x ) - 2x
A´(x) = 0 ⇒ 2400 - 4x = 0 ⇒ 4x = 2400
x = 600 m
And y = 2400 - 2*x
y = 2400 - 1200
y = 1200 m
And the largest enclosed area is Amax = 1200*600
Amax = 720000 m²
