Question

A party of 8 fishermen rented a boat. Two of the fishermen had to withdraw from the party and, as a result, the share of each of the others was increased by $4 . What is the total cost of the boat rental (in dollars)?

Answer 1

$96

Explanation:

let the the amount each men pay when they were 8 be x

let the total amount for the boat rental be y

8x=y .....................equ1

if two men withdraw from the party, and the amount each men pay increases by $4 then;

(x+4)6 =y

6x+24=y ...........equ2

make x the subject of formula from equ1;

x=y/8

substitute x as y/8 into

6(y/8) +24 =y

3y/4 +24=y

24=y-(3y/4)

`24=(4y-3y)/(4)`

24=y/4

y=24*4

y=$96
