Seth sells candles for $14.35 each. Last week, he sold 21 candles over 4 days. Seth
pays $2.40 for materials for every 3 candles.
How much did Seth earn last week?

284.55

Step-by-step explanation:divide 21 by 3=7  7times 2.40=16.8           14.35 times 21=301.55

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:
