Answer:
Alex had $196.54 in her account before the purchase.
Step-by-step explanation:
Given:
Amount spend on medicines = $35.31
Balance Amount Remaining = $161.23
We need to find the amount in her account before purchase.
Solution:
Let the amount in her account before purchase be 'x'.
Now we can say that;
Amount in her account before purchase minus Amount spend on medicines is equal to Balance amount remaining.
framing in equation form we get;
Now by Using Addition property of equality we will add both side by 35.31 we get;
Hence Alex had $196.54 in her account before the purchase.

The discriminant is-
b^2-4ac=64-64=0
as the discriminant is 0, one solution will be -b/2a = -1/2
But still, we can't say that it has only one solution due to the nature of quadratic equations(It's tendency to have two solutions).
But we can say that both solutions are coincident.
Hence it has two solutions.

He would have $750 at the end of three weeks
500 + 200 = 700 700 x 2 + 1400
1400 - 650 = 750
