The entry to a fair costs Rs 20 and each game at the fair costs Rs 5 to play. If Shalini went to the fair and the number of games she played is x, write an expression for the total money spent.
5x + 20
Total money spent = Cost of entrance + Cost of playing games
Cost of entrances = Rs 20
Cost of playing x games = 5x
Total money spent = 5x + 20
