Will give extra state the domain, range, x-intercept, and y-intercept of each word problem. also decide if the domain should only include whole numbers. (i only need the domain and range) an amusement park charges $8.25 for an adult meal and $6.50 for a child meal at its food stand. at the end of the day the food stand had collected $2,145. this situation can be modeled by the equation 8.25x + 6.5y = 2145 where x represents the number of adult meals sold and y represents the number of child meals sold.
