Sean had $45.50 in his account. he bought books worth $3 more than what he had in his account. graph the point that represents the balance of sean’s account.

( 48.5, -3 )    

Step-by-step explanation:    

Suppose x-axis shows the withdrawing amount (in dollars) and y axis shows the balance ( in dollars ) after withdrawing x amount,

Here, the Initial amount = $45.50,

Thus, the equation that shows the given situation is,

y = 45.50 - x

Since, Sean bought books worth $3 more than what he had in his account,

That is, x =  48.50,

⇒ y = 45.50 - 48.50 = -3

In the coordinate plane the point are represents by the notation (x,y),

So, the point that represents the balance of Sean’s account is (48.50, -3).
