A girl bought a card and then returned it. The second card cost $1.50 less than the first card. She got 75 cents in change. How much did the first card cost?

Let x equal the cost of the first card.

x - 1.5 = 0.75
x = 0.75 + 1.5
x = 2.25

Does that make sense to you?

To find out how much the first card cost, let's break down the information given.

Let's assume that the cost of the first card is x dollars.

According to the problem, the second card costs $1.50 less than the first card. Therefore, the cost of the second card is (x - $1.50).

The girl paid for the first card and received 75 cents in change. This means that she paid (x - 0.75) dollars for the card.

According to the problem, she later returned the card. This means that she was refunded the full amount she paid, which is (x - 0.75) dollars.

Since the second card cost (x - $1.50) and she received a refund of (x - 0.75) dollars, we can set up an equation:

(x - 0.75) = (x - $1.50)

To solve this equation, let's eliminate the variables on both sides:

x - 0.75 = x - $1.50
x - x = -1.50 + 0.75 (by canceling out the x's on both sides)
0 = -0.75

This equation doesn't make sense since 0 cannot be equal to -0.75. Therefore, there seems to be a contradiction in the information provided.

Please double-check the given information to see if there are any errors.
