Question

Emma went to the movie theater for her birthday. A mix of adults and children attended, making a total of 19 people. Each adult ticket was $9 and each child’s ticket was $5.50. If the total cost for the party was $150, then how many adults and how many children attended ?​

Answer 1

Answer:

no. of adults=x

no. of children= 19-x

cost of adults= 9x

cost of children= 5.5(19-x) =104.5-5.5x

104.5 -5.5x+9x= 150

104.5+3.5x= 150

3.5x= 150-104.5

3.5x= 45.5

x= 45.5/3.5

x= 13

adults=13

children=19-13=6
