Answer:

Step-by-step explanation:
See attachment for grid
From the attachment:
There are 10 cells on the horizontal axis and there are also 10 cells on the vertical axis.
This implies that, the measurement of each cell is:



The horizontal axis has 7 selected cells.
This measures

The vertical axis has 4 selected cells.

or

Using proportions, it is found that the minimum payment the hospital will accept from the patient is of $50.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
15% of the balance of $350.00 is given by:
B = 0.15 x 350 = $52.5.
Which is a higher amount than $50, hence the minimum payment the hospital will accept from the patient is of $50.
