With each of them saving $17 a week for 3 weeks, they will be able to save up $153 after three weeks. Adding this amount to the original amount they had will give them $467. Obviously, they will not have enough money to buy the gift they want for their mother. They will be short of $48.

x(x-)(x+)
x(x-8)(x+8)
