Question

The Jurassic Zoo charges $13 for each adult admission and $4 for each child . The total bill for the 238 people from a school trip was $1330. How many adults and how many children went to the zoo ?

Answer 1

Answer:

42 adults and 196 children went to the zoo

Step-by-step explanation:

Let

x ----> the number of adults

y ----> the number of children

we know that

The total bill for the 238 people from a school trip was $1330

so

$x+y=238$ ----> equation A

$13x+4y=1,330$ ----> equation B

Solve the system of equations by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

the solution is the point (42,196)

see the attached figure

therefore

42 adults and 196 children went to the zoo
