Answer:
P = 128 Post
Step-by-step explanation:
Total post needed = 216 posts
Number of post Jerry has = 88 posts
Number of posts jerry still needs = P
Total = Number of post Jerry has + Number of posts jerry still needs
216 = 88 + P
216 - 88 = P
128 = P
P = 128 Post

Step-by-step explanation:
The point-slope form of a line is given by:

The line given to us has equation;
.
The slope of this line is -4. The of the line perpendicular to this line is the negative reciprocal of the slope of the given line.
Our slope of interest is therefore; 
Since the point goes through (-2,7), we have
.
We plug in the slope and the point into the point-slope formula to obain;

The required equation is:

Answer:
probably b

Step-by-step explanation:
If we want to calculate the full prize we need to calculate how much the tax was:
420* 17

%=420*

=420*

=21*

=73.5
so this is how much the tax was.
and the full prize is the cost of the ring and the tax: 420+73.5=493.5
so that's how much the buyer will pay
