Answer:
The equation that represents the situation is 10x + 20y = 150.
She can buy 15 T- shirts with the money she has.
Step-by-step 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.
