To celebrate their wedding anniversary, Derek and Lucy decided to spend the night out on the town. After dinner, which incidentally cost them one-third of the money they had brought with them, they purchased two theater tickets at $9.80 each. After the show, they spent one-fourth of their remaining bankroll for a taxi ride around the city. They then went to get desserts, where their total cab came to $23.10. The cab fare home cost them one-half of their remaining money. After they had tippled the driver a dollar, they had $4.10. How much did their celebration cost them?

let total money=x x = x/3 + 9.8 + [x-{(x/3)+9.8}]/4 + 23.10 + [x-{x/3 + 9.8 + {x-{(x/3)+9.8}}/4 + 23.10}]/2 + 1 + 4.10 solve the above to get x=81.3 From tutor vista Answers
