Answer:
75 cents or $0.75
Step-by-step explanation:
1. We see that Shirley takes the train to work and back home. This means she takes the train twice a day. We also see that she uses the train five times a week. So step 1, multiple 5 and 2.
5x2 = 10
2. She pays $25 for a weekly train pass. Divide 25 and 10.
25/10 = 2.5
3. Now, we compare how much money she saved. Subtract 3.25 and 2.5.
3.25-2.5 = 0.75
4. This means she saved 75 cents by purchasing the weekly pass.
