Then, the maximum height is 136 ft
The price of each ball in a baseball bag would be 1.665 dollars
It is given that,
The cost price of a bag of baseball bag = 9.99 dollars
The number of balls in each bag = 6 baseballs

To find the cost of one quantity out of a bunch we divide the bunch price with the number of quantities in the bunch
Here, in this case
The cost price of each ball =
=
= 1.665 dollars
Hence, the price of each ball in a baseball bag would be 1.665 dollars
