Total cost for the trip = $800.
Let x = original number of friends.
Therefore the equally shared cost of the trip for each friend is $800/x.
After 2 friends drop out, the cost for each friend increases to $800/(x-2).
The increase in cost for each remaining friend is $20, therefore
Divide through by 20.
Cross multiply.
x(x - 2) = 80
x² - 2x - 80 = 0
(x + 8)(x - 10) = 0
x = -8 or 10
Reject x = -8 because we cannot have a negative number for friends.
x = 10

Explanation:
We need to recalcualte the desired ending inventory
as currently they are calcualte at 20% and we want it at 25% we do cross multiplication
Jan: 7,540 / 20 x 25 = 9,425
We divide by 20 to get the value of a single percent f sales and then we multiply to 25 as it is our desired amount
Feb: 6,500 / 20 x 25 = 8,125
March: 2,770 / 20 x 25 = 3,462.5
Next we adjsut6 the beginning inventory for January as it is 2,770 instead of 4,900 and we can determiante the production budget need for the quarter
