Step-by-step explanation:

-Long way

1.) Add all the numbers of people together (60)

2.) Divide all the students aka.540 by 60. (9)

3.) Multiply 9 by all the numbers.

=Answer for all. (Double check)

-Mental math

1.) look at chart

2.) compare 8 and 7

3.) figure out which is larger.

=Answer of A

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:
