34. a.Start with the money she had left and work backwards. If she had $5 left over, and had just spentthree-fourths of her money on food, then $5 must be one-fourth of her money. Before buying foodshe must have had 5 ×4 = $20. She then spent half of her money on clothes; therefore, $20 was half ofher money, giving her $40 at this point. She then spent one-third of her money on books and had $40left over. If $40 represents two-thirds of her money, then $60 must be the amount she began with.
