Question

Select the correct answer from each drop-down menu. A store sells T-shirts for $10 each and jeans for $20 a pair. Anna spends $150 on T-shirts and jeans. She buys x T-shirts and y pairs of jeans. The equation that represents the situation is . If Anna decides to buy only T-shirts and no jeans, she can buy T-shirts with the money she has.

Answer 1

Anna wil buy a total of 15 shirts without buying pants because 150 divided by 10 is 15.

Answer 2

The equation that represents the situation is 10x + 20y = 150.

She can buy 15 T- shirts with the money she has.

Explanation:

Here, x represents the number of T-shirts bought and y represents the number of pair of jeans,

Part 1 : Since, each shirts costs $10 and each pair of jeans costs $ 20,

Thus, her total sending = 10x+20y

According to the question,

10x + 20y = 150 -----(1)

Which is the required equation that represents the situation.

Part 2 :

If Anna decides to buy only T-shirts and no jeans

Then y = 0,

From equation (1),

10x = 150

⇒ x = 15

Thus, she can buy 15 T- shirts with the money she has.
