Answer 2

The equation that represents the situation is 10 X + 20 Y = 150

She can buy 15 T shirts

Explanation:

Price of T shirt = $10

Price of Jeans = $20

She buys X T-shirts and Y pairs of jeans and Anna spends $150 on T-shirts and jeans.

Equation for this

10 X + 20 Y = 150

If Anna decides to buy only T-shirts and no jeans(y=0)

10 X + 20 x 0 = 150

X = 15

So she can buy 15 T shirts
