students cut 5 and three-fourths inches of thread from a spool for a school project. What number represents the change in the amount of the thread on the spool?Negative 40 and one-fourth inchesNegative 35 and three-fourths inchesNegative 29 and three-fourths inchesNegative 26 and one-fourth inches

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:
