Inequality: x = the number of pounds of grapes
2.75x < 9.35 [2.75x is less than 9.35, since Drew must spend less than $9.35]
Solution:
To find the solution, you need to isolate/get "x" by itself in the inequality.
2.75x < 9.35 Divide 2.75 on both sides to get "x" by itself
x < 3.4
Interpretation:
x is less than 3.4, so Drew has to buy less than 3.4 pounds of grapes in order to spend less than $9.35 [which is the most/maximum $ he has]

Answer:
The greatest area of rectangle is:
625 square units.
Step-by-step explanation:
It is given that:
A rectangle of perimeter 100 units has the dimensions as:
50-w on the top and bottom.
and a w on its left side and right side.
i.e. we may say the length of the rectangle is:
50-w
and the width of the rectangle is:
w
Now, we need to find the greatest area of rectangle.
As the area of rectangle is:
A = w(50 - w)=50w-w^2
Now, to find the maximum area we differentiate the Area with respect to the width as:
Hence, to obtain the maximum area the width of the rectangle is: 25 units.
and that of the length of the rectangle is:
50-25=25 units.
Hence, the dimensions of rectangle in order to obtain the maximum area is:
25 units by 25 units.
So, the area of rectangle is:
Hence, the greatest area of rectangle is:
625 square units.
