document.write( "Question 1108699: at a travel agency the cost of a trip to Mexico is $350 for an adult and 200 for child one month the travel agency sold 50 trips of these trips, y trips were for children the travel agency collected c dollars for selling 50 trips. Write a linear equation for c in terms of y. Express y in terms of c and if $15,250 was collected, find the number of children going on the trip
