The 2020 senior class from a high school raised funds for an end of the year prom at Club Dance. It costs $4,000 to rent out Club Dance plus $20 per student for food and drinks. Write an equation for the number of students could attend if the senior class raised 11,000 dollars.

4000 + 20x = 11,000

Step-by-step explanation:

4000 + 20x = 11,000

20x = 7,000 (subtract 4,000 from 11,000)

7,000/2 = 3500

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:
