Can someone me with this question that starts off with "brad has $"?

He will get back 5.25 in change

Step-by-step explanation:

The cost for 1/2 lbs of sausage

Cost = rate * amount

       = 3.25 * .5

        =1.625

1 1/4 lbs of chicken

Cost = rate * amount

       = 2.50 * 1.25

          3.125

To total of his purchases is

1.625+3.125=

4.75

He has 10 dollars

10-4.75 = change back

5.25

He will get back 5.25 in change

$5.24

Step-by-step explanation:

If a pound of sausage is $3.25, and Brad bought 1/2 a pound, he spent $1.63 on sausage.

If a pound of chicken is $2.50, and Brad bought 1 1/4 pounds, he spent $3.13 on chicken.

In order to find out how much money he has left, you have to subtract what he spent from $10.

He spent: $3.13 + $1.63 = $4.76

How much he has left: $10 - $4.76 = $5.24.

Let me know if I went into enough detail :)

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.
