Answer:
-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
7/8*8/9 = (7*8)/(8*9)
Since we have an 8 both above and below, we can erase it, and so the answer is 7/9
Step-by-step explanation:
the second equation should be multiplied by 9
