The total amount of paint needed is 15 quart and it cost $41.25.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
0.0015 quart of paint to cover 1 square inch.
Let the area of the rectangle be 10000 in², hence:
Amount of paint = 0.0015 quart per in² * 1000 in² = 15 quart
Cost of paint = $2.75 per quart * 15 quart = $41.25
The total amount of paint needed is 15 quart and it cost $41.25.

Yes it is linear since it's in the standard form Ax+By = C
A = 2
B = -8
C = 16

Answer:
The value of x that maximizes the volume enclosed by this box is 0.46 inches
The maximum volume is 3.02 cubic inches
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The volume of the open-topped box is equal to

where

substitute

Convert to expanded form

using a graphing tool
Graph the cubic equation
Remember that
The domain for x is the interval -----> (0,1)
Because
If x>1
then
the width is negative (W=2-2x)
so
The maximum is the point (0.46,3.02)
see the attached figure
therefore
The value of x that maximizes the volume enclosed by this box is 0.46 inches
The maximum volume is 3.02 cubic inches
