child admission is $ 6.50 and adult admission is $ 9.90 .147 tickets were sold for a total sales of $ 1258.10 how many child tickets were sold

58 children's tickets were sold!

Step-by-step explanation:

c=# of children's tickets sold

a=# of adults' tickets sold

6.5c+9.9a=1258.10

c+a=147

a=147-c

6.5c+9.9(147-c)=1258.1

6.5c+1455.3-9.9c=1258.10

(subtract 1455.3 from both sides)

6.4c-9.9c=-197.2

-3.4c=-197.2

(divide by -3.4 on both sides)

c=58

Hope this helps!! :D
