A company’s sales decreased 5% this year to $6,585. What were their sales last year?

$6932

Step-by-step explanation:

Let last year's sales = x.  Since there was a decrease of 5%, that means this year's sales are 95% of last year's sales.

So, .95x = 6585

x = 6932 to the nearest dollar

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.

you can't solve x because it is 2 linear equation and you only have one equation
