Answer:
480 glasses
750 plates
1230 dishes altogether
Step-by-step explanation:
If each box holds 16 glasses and she bought 30 glasses you times the 16 by 30 to get 480.
Then there are 25 plates in each box and she bought 30 boxes you multiply those numbers together and get 750
Last you add the two numbers together and get 1230 dishes
The given expression is equivalent to

<h3>What is a quadratic expression?</h3>
A quadratic expression is a second-degree algebraic expression represented by the:
........(1)
Where a, b, and c are the constants and
We have a quadratic expression:
Convert it to perfect square by perfect square trinomial:
(adding and subtracting by 49)
Here 
is the positive term and -2 is the negative term so in order to get the highest weekly profit it should be zero, so
x = $7
Thus, the given expression is equivalent to and the price is $7.

To find the slope when you are given the graph, you need to find the change of y over the change in x. First, choose two points on the line. I picked (0,2) and (5,-2). By counting boxes, determine the change in y, which is -4. Then determine the change in x which is 5. So your slope is -4/5
