Question 483747: a local bus tour sold 65 tickets. senior citizen tickets cost $10 and regular tickets cost $15 the total sales were $855. how many of each type of ticket were sold? Answer by mananth(16949) (Show Source):
1 x + 1 y = 65 .............1
10 x + 15 y = 855 .............2
Eliminate y
multiply (1)by -15
Multiply (2) by 1
-15 x -15 y = -975
10 x + 15 y = 855
Add the two equations
-5 x = -120
/ -5
x = 24
plug value of x in (1)
1 x + 1 y = 65
24 + 1 y = 65
1 y = 65 -24
1 y = 41
y = 41
Senior citizens 24 tickets
regular 41 tickets
