When Mr. J. Raff took his two children to the zoo,their tickets cost \$8.75. The next family in line was Mrs. Ella Fant with Grandpa and the five Fant kids. Their tickets cost a total of \$19.75. How much does the zoo charge for each adult and for each child?

@Lindastanich,
Working in cent,let a=cost per adult, c=cost per child

a+2c=875
2a+5c=1975

Method...double first equation and subtract from second to eliminate 2a, giving c. Then use c that to find a.
