The amount of the baseball cards for each card is $0.60, which is the quotient of $9.00 divided by 15.
The quotient is the result of a division operation, involving the dividend (the numerator) and the divisor (the denominator).
The total number of baseball cards that Noah bought = 15
The total cost for the cards = $9.00
The unit cost = $0.60 ($9.00 ÷ 15)
Thus, we can conclude that the unit price or cost for each baseball card is $0.60.
