Question

MR THOMAS TOOK HER FAMILY AND FRIEND TO THE MOVIES THERE WERE 16 PEOPLE . CHILDREN TICKERS COST $6 AND ADULTS TICKETS COST 9 SHE SPENT A TOTAL OF $1219 HOW MANY ADULTS WENT TO THE MOVIES

Answer 1

a = 374

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.
