Remember: A jar adds nothing. A savings account keeps coins safe and pays a small yearly extra called interest. These are pretend coins; real accounts differ, so ask a grown-up to read the fine print.
Read and answer
Read the story first, then answer.
Maya and the bikeMaya wanted a bike that cost 440 pretend coins, and she had 400 in her jar. So close! She was not adding more, so the coins just sat there, and after two years the jar still held 400. That was 40 short of the bike, because a jar adds nothing. Gran said there was another way: a savings account at the Coin House. You lend the house your coins, and it keeps them safe and pays extra. That extra is called interest, and Maya could take her coins back any day. The pretend rule was one extra coin for every twenty, each year. Maya handed over 400, and the clerk wrote it in the ledger. In year one, 400 held twenty twenties, so 20 extra coins arrived and the balance was 420. In year two, 420 held twenty-one twenties, so 21 arrived, and the balance was 441, because the extra earned extra. Maya took out 440 for the bike, and one coin stayed behind. These numbers are made up. Real accounts pay different amounts that change, and some charge fees, so a grown-up can read the fine print.

Savings accounts
140 440 − 400 = 40.
2True She added nothing, and a jar adds nothing, so the jar still held 400.
3Interest The extra is called interest. In this made-up Coin House it is 1 extra coin for every 20, each year.
43 60 is three twenties, so the extra is 3.
5420 400 + 20 = 420.
621 21 × 20 = 420, so 21 extra coins arrive and the balance becomes 441. The extra earned extra.
7The account paid a yearly extra, and the jar adds nothing Both started with the same 400 coins. Only the account paid the extra.
81-B, 2-D, 3-C, 4-A A jar adds nothing, the ledger holds the account, interest is the extra, and a statement lists the changes.
92, 4, 3, 1 Jar first, then the account, then 420 after year one and 441 after year two.
10No 441 − 440 = 1, and the story says one coin stayed behind.
11False These numbers are made up. Real accounts pay different amounts that change, and some charge fees.
1225 500 holds twenty-five twenties, since 25 × 20 = 500, so the extra is 25.
