Question

The jurassic zoo charges $5 for adults and $2 for children, the total bill for 144 from a school trip was $396. How many adults and how many children? @Mathematics

Answer 1

Let A=Adults
Let C=Children

5A+2C=396
A+C=144 Multiply this equation by 2 to find A

5A+2C=396
2A+2C=288 Subtract this equation from the above to find A

3A=108
A=36

A+C=144
C=144-36
C=108

Therefore, there are 36 Adults and 108 Children
