James bought two T-shirts and one pair of jeans at an online store and paid $40, not including taxes, for his purchase. A month later, the same store sold the T-shirts and jeans at a 50% discount from their original prices. James bought two T-shirts and five pairs of jeans for $60, not including taxes.

Assuming the base prices of the T-shirts and the jeans are the same on both occasions, and ignoring the taxes, the price of a T-shirt is $_

and the price of a pair of jeans is $_

The price of a t-shirt is $10 and the price of a pair of jeans is $20.

Step-by-step explanation:

Step 1:

Assume the cost of one t-shirt is x and the cost of one pair of jeans is y.

From the question,

, take this as equation 1,

For the second scenario, there was a 50% discount, so we multiply the total price i.e $60 by 2 to form equation 2.

, take this as equation 2.

Step 2:

When we subtract equation 2 from equation 1, the x variable is canceled out and y can be calculated.

Step 3:

Substituting this value of y in any of the previous equations we will get x's value.

Here this value of y i.e is substituted in equation 1.

So we have and So the price of a t-shirt is $10 and the price of a pair of jeans is $20.

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.
