Each flea treatment usually last for about 4 weeks, but 1 year the fleas were especially bad. jim's dog needed to be treated every 3 weeks until the weather cooled off. how many weeks of flea treatments would jim's dog get from one package of each treatment only lasted 3 weeks. in a normal year when a flea treatment last 4 weeks, how many more weeks of treatment would jim's dog get from one package

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:

the answer is b.)

< 1=< 2

the two may have that, even a breakdown is probably offered
