Quinn had $4.00. He spent 1/2 of his money on a baseball card, 1/4 of it on a drink, and 1/8 of it on bubble gum. How much money does Quinn have left?
A
$0.25
B
$0.50
C
$1.00
D
$1.25
He spend 1/2 A + 1/4 A + 1/8 A
that is A(4/8 + 2/8 + 1/8)=7A/8
well, A is 4.00, so he must have 1/8*4.00 left. I think that is fifty cents.

To find out how much money Quinn has left, we can subtract the amounts he spent from the $4.00 he originally had.
First, let's find out how much Quinn spent on the baseball card. He spent 1/2 of his money on it. To do this, we divide $4.00 by 2: $4.00 ÷ 2 = $2.00.
Next, let's find out how much Quinn spent on the drink. He spent 1/4 of his money on it. To do this, we divide $4.00 by 4: $4.00 ÷ 4 = $1.00.
Lastly, let's find out how much Quinn spent on bubble gum. He spent 1/8 of his money on it. To do this, we divide $4.00 by 8: $4.00 ÷ 8 = $0.50.
Now, let's add up the amounts Quinn spent: $2.00 (baseball card) + $1.00 (drink) + $0.50 (bubble gum) = $3.50.
To find out how much money Quinn has left, we subtract the total amount he spent from the original $4.00: $4.00 - $3.50 = $0.50.
Therefore, Quinn has $0.50 left.
So, the correct answer is B. $0.50.
