On the first day of his backpacking trip, Andy left camp at 9:15 A. M. and arrived at his new
camp at 4:45 P. M. His average rate of speed was
2 1/2 miles per hour. On the second day he left
the new camp at 8:45 A. M. and arrived at his
final camp at 3:30 P. M. His average rate of speed
was 3 miles per hour. Find the total distance
that he hiked over the two days.

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 correct answer is 1: 2
