How it works
A wage pays so many coins for each hour of work.
Mrs Pell paid Omar 3 coins for every hour. Each hour adds the same 3 coins.
More hours means more pay: 1 hour is 3 coins, 2 hours is 6, 3 hours is 9, and 4 hours is 12.
Pay day is the day a helper gets paid. Hours worked, times the pay for each hour, makes the wage.
