SPENT A TOTAL OF $1219 HOW MANY ADULTS WENT TO THE MOVIES
1 answer:
Answer:
a = 374
Step-by-step explanation:
Given that:
Cost of children ticket = $6
Cost of adult ticket = $9
Total amount spent = $1219
Total number of people = 16
Let :
Children = c
Adult = a
a + c = 16 - - 1
6c + 9a = 1219 - - - 2
From 1
c = 16 - a
Using 2
6(16 - a) + 9a = 1219
96 - 6a + 9a = 1219
3a = 1123
a = 374.33
Adult = 374.33
The number should be a whole number, maybe there is a problem with the parameters given.
