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

10x + 20y =150

10x + 20 (0) = 150

10x + 0 = 150

10x = 150

x = 15 Tshirts

Explanation:

Answer 2

1.
`10x+20y=150`

2. 15 t shirts

Explanation:

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
`10x+20y=150`

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

Means y = 0

So,
`10x+20(0)=150`

`10x=150`

x = 15

Hence, she can buy 15 t shirts.
