Jack divided his fortune of $92,000 into 8 equal portions. He gave 4 portions to his wife, 1 portion to his son and divided the remaining portions equally among 5 charities. How much more money did his son get than each charity?
$.00
One portion is $92,000 ÷ 8 = $11,500.
Since Jack gave 4 portions to his wife and 1 portion to his son, he gave 8 – 4 – 1 = 3 portions to charities.
Therefore, the charities received 3 × $11,500 = $34,500 altogether.
Then each charity received $34,500 ÷ 5 = $6,900.
Since his son received one portion of $11,500, his son received $11,500 – $6,900 = $4,600 more than each charity.
