Working mothers who earn $30,000 or less per year receive a rebate on before and after school care of 75%,plus a school bonus of $6,000 that only applies to this categoric of earnings. Each dollar earned above this amount and up to $40,000 reduces the rebate to 55%, and for any amount above this, the rebate drops to 30%. There are three mothers - Jade earns $40,001, Emily earns $38,000 and Lucy earns $29,550. If the cost of before and after school care is $10,000 per year, what amount of money does the person have who has the least amount of money left after paying for before and after school care?
