When de'andre goes to work, he drives at an average speed of 60 miles per hour. it takes about 1 hour and 45 minutes for him to arrive at work. his car travels about 30 miles per gallon of gas. if gas costs $3.55 per gallon, how much money does he spend to travel to work and back home every day?

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:

answer: the anser is 3
