Sean has a beginning balance of $328.15 in his account. He writes checks for the following amounts: $20.75, $43.58, $30.45, and $29.72. What is the new balance in Sean's account?
$14.75

$203.65

$124.50

$307.40

The new balance in Sean's account is $203.65

Step-by-step explanation:

The initial balance in Sean's account is $328.15. Then he writes checks for the amounts $20.75, $43.58, $30.45, and $29.72.  

The sum of his checks is $20.75 + $43.58 + $30.45 + $29.72 = $124.5

The new balance in Sean's account is the initial balance minus the sum of the amounts of the checks he wrote:

Final balance = $328.15 - $124.5 = $203.65

The new balance in Sean's account is $203.65

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
