Question

One afternoon the water park sold 525 tickets for a total of $13,545. Child tickets cost $19 each, and adult tickets cost $40 each. How many of each kind of ticket were sold?

Answer 1

Answer:

child tickets sold =355

adult tickets sold=170

Step-by-step explanation:

let the child tickets be =x

cost for one child ticket =19

cost for x child tickets =19x

adult tickets be =y

cost for one adult ticket=40

cost for y adult tickets=40y

x+y=525

x=525-y. .........1

19x+40y=13545. .........2

put the value of x in eq 2

19(525-y)+40y=13545

9975-19y+40y=13545

21y=13545-9975

21y=3570

y=170

Now put the value of y in eq 1

x=525-170

x=355
