Question

80 people have bough tickets to The Great Bombay Circus. The circus has
collected a total of 6300 from the ticket sale. If the cost of an adult ticket is
590 and the cost of a kid ticket is 60, how many kid tickets were sold?​

Answer 1

Answer:

30

Step-by-step explanation:

Adult(A) = 80-kid(K)

90A+60K=6300

90(80-K)+60K=6300

7200K -90K+60K=6300

30K=7200-6300

30K=900

K=30

A=50

Answer 2

There were 30 kids.

Step-by-step explanation:

Consider:

Adult(x) = 80-kid(y)

90x+60y=6300

90(80-y)+60K=6300

7200y -90y+60y=6300

30y=7200-6300

30y=900

y=30

x=50
