(1 point)
• Mrs. Hayakawa would save $60.
• Mrs. Hayakawa would save $120.
• Mrs. Hayakawa would save $168.
• Mrs. Hayakawa would save $24.

Mrs. Hayakawa works 5 days a week for five weeks, which is a total of 5 * 5 = <<5*5=25>>25 days.

If she takes the bus to work, the round trip would cost 2 * $2.40 = $<<2*2.40=4.80>>4.80.
Over the course of 25 days, taking the bus would cost her 25 * $4.80 = $<<25*4.80=120>>120.
If she walks instead, she would save $120. Therefore, the correct answer is:
• Mrs. Hayakawa would save $120.
