Answer:
lol
Step-by-step explanation:
X= child ticket
y= adult ticket
COST EQUATION:
$5.90x + $9.70y=$1352.20
QUANTITY EQUATION:
x+y=168
Step 1:
Solve for one variable in either equation and substitute it in the other equation
x+y=168
subtract y from both sided
x=168-y
Step 2:
substitute x=168-y in other equation
5.90x + 9.70y=1352.20
5.90(168-y) +9.70y=1352.20
multiply 5.90 by everything in parentheses
(5.90*168)+(5.90*-y) +9.70y=1352.20
991.20-5.90y+9.70y=1352.20
combine like terms
991.20+3.80y=1352.20
subtract 991.20 from both sides
3.80y=361
divide both sides by 3.80
y=95 adult tickets
There were 95 adult tickets sold.
Hope this helps! :)
