-6.20x-6.20y=-948.6

add this to equation 2

6.20x-6.20x + 9.30y-6.20y=1125.30-948.60

3.10y = 176.70

/3.10

y=176.70/3.10

y = 57 number of adult tickets

153-57=96 child tickets

Step-by-step explanation:

child admission is $6.20 : x numbers

adult admission is $9.30 : y numbers

153 tickets were sold

sales of $1125.30.

x+y = 153 ... 1

6.20x+9.30y = 1125.30 ... 2
