Thread: help with algebra word problem

Hi everyone I need help in determining the the number of children that went to the restaurant how would I do that?

The Hungry Heifer diner offers an all-you-can-eat buffet at $25.90 per adult and $17.90 per child. On a particular day, the diner had total buffet revenue of $6,609.40 from 266 customers.

How many customers were children?

Adults $25.90
Child $17.90
Total customers 266
Revenue $6 609.40

Thanks any help would be appreciated

Let x be adults and y be children.
