a.)$41.43

b.) $37.68

c.) $36.35

d.) $24.27

We have been given that the admission to the museum is $12.50 plus tax. Zalia pays for herself and her friend.  

Let us find cost of two admission tickets.  

Cost of tickets after 7.25%tax would be

They have lunch at the museum’s cafe. Zalia has a sandwich for $5.95, an apple for $1.25 and a drink for $1.69.

Now we will find cost of lunch after 15% tip.  

Total cost of trip would be .

Therefore, Zalia will pay $37.78 in total for her day at the science museum.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
