Answer:
Step-by-step explanation:
We can write two equations in the two unknowns using the given relations. Let g and b represent the costs of a round of golf and a turn in the batting cage, respectively.
5g +4b = 60 . . . . . Sylvester's expense
3g +6b = 45 . . . . . Lin's expense
Dividing the second equation by 3 gives ...
g +2b = 15 ⇒ 2b = 15 -g
Substituting into the first equation, we have ...
5g +2(2b) = 60
5g +2(15 -g) = 60 . . . . . substitute for 2b
3g = 30 . . . . . . . . . subtract 30, collect terms
g = 10 . . . . . . . divide by 3
__
2b = 15 -10 = 5 . . . . use the value of g to find b
b = 2.5 . . . . . . . . divide by 2
Mini golf costs $10 per round; batting cages cost $2.50 per turn.

EXPLANATION
Let us find the gradient of the line:
by rewriting it in the slope intercept form.

We divide through by 4 now;

This is now in the form;

where
is he slope.
This implies that the slope of the line that is perpendicular to this line will be the negative reciprocal of
.
Thus the perpendicular line has slope,
.
Let the perpendicular line have equation,

When we substitute the slope we have;

We substitute the point.
to find c.



We substitute c to obtain;
