Jamie has a plan to save money for a trip. Today, she puts 5 pennies in a jar. Tomorrow, she

will put the initial amount in plus another 5 pennies. Each day she will put 5 pennies more

than she put into the jar the day before, as shown in the table. Let f(d) represent the number of pennies she puts into the jar on day d. What does f(10) = 55 mean?

• Jamie will put 10 pennies in the jar on day 55.

• Jamie will put 55 pennies in the jar on day 10.

• Jamie will have 10 pennies in the jar on day 55.

• Jamie will have 55 pennies in the jar on day 10.
