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 ?

Let x be the number of adult tickets, and let y be the number of children's tickets.  You can then write down the equations, and solve.

x = adult tix                 13x     =        money from adult tix

238 - x = child tix         4 ( 238-x)  = money from child tix        add money amounts together to equal  $ 1330

 

13x    +    4 (238-x) = `1330      solve for 'x' , the number of adults, then number of child =   238-x
