Justin and George bought some baked goods. Justin purchased 5 cookies for x dollars each and 4 doughnuts for y dollars each and spent $12 dollars on the baked goods. George purchased 1 cookie for x dollars each and 6 doughnuts for y dollars each and spent $5. The system of equations represents this situation. Which statement is true?

5x+4y=12
x+6y=5

Justin spent more on doughnuts than he did on cookies

Justin spent $4 on each doughnut

A cookie cost $1.50 more than a doughnut

George spent 6 times as much on doughnuts as he did on cookies

55/i dont know i do it for the points

step-by-step explanation:

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
