Lara is in charge of ticket sales for the school play. a student ticket costs $4.50 and an adult ticket costs $8.50. if every adult brings at least one student with him or her, and the school auditorium holds 658 ple, what is the maximum amount of money lara can collect for one night? provide equation and explanation if you want

450 is the final answer! : )

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
