Question

zpupster · Answer

we have two unknowns child and adult so we should have 2 equations

child = x
adult=y

we know

 x+y = 168  equation 1

and price times no of child tickets money from child tickets
the same with adults and the we know the total  1316.40

5.80x + 9.60y = 1316.40

zpupster · Answer

x+y = 168 
solve by subtracting x from both sides
y= 168-x
 plug this in for y

5.80x + 9.60(168-x) = 1316.40  solve for x then plug back to solve for y
