Gradient is just another similar term for slope l,
, and it can be calculated by
where
and 1
is the
-coordinates of point 
We let
be point
and
be point
, we can then write the equation:
.
It also says that the points are with a gradient of
so
. We can then write the equation:

Price = 
⇒ 
⇒ 
⇒ 
⇒ 
Now, The sales tax rate was 5%. So , total amount to be paid is :
⇒ 
⇒ 
⇒ 
Bruce have $35 which is greater than amount to be paid i.e. $30.87 . So , Bruce have enough money to buy the game .
