Answer:a party of fishermen rented a boat for $240. two of the fishermen had to withdraw from the party and, as a result, the share of each of the others was increased by $10. how many were in the original party? provide a numerical answer.

Explanation:

Now ,Let original number in party be "x"::

Average cost per person = 240/x

New number in the party:: x-2

New Average cost per person:: 240/(x-2)

Equation::

10 dollars =New average - old average

240/(x-2) - 240/x = 10

240x - 240(x-2) = 10x(x-2)

480 = 10x^2-20x

x^2 - 2x - 48 = 0

X = 8 (ORIGINAL)
