Problema Solution
A group of 19 student want to see the show at the planetarium. Tickets cost $11 for each student who is a member of the planettarium's frequent visitor program and $13 for each student who is not a member. The total cost of the students' tickets is $209.
Answer provided by our tutors
Let 'm' stand for the number of member tickets and 'n' stand for the number of non-member tickets. From the given, we can write:
n+m=19
11m+13n=209
using Algebrator to solve for 'm' and 'n', we get:
m=19
n=0
All of the students are members.
