Question

Solving a word problem with two unknowns using a linear...A total of 432 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times thenumber of adult tickets sold. How many adult tickets were sold?

Answer 1

1) Gathering the data

Adult tickets + Student Tickets = 432

a 3s

Setting the linear system:

a+s=432

a=3s

2) Plugging into the first equation

3s +s =432

4s=432 Dividing by 4

s=108

Since a +s = 432 then we can say

a =432-s
