Read and answer

Read the story first, then answer.

Ana borrows from LenaAna made baskets for the village market, but reeds cost ten pretend coins and she had none. Lena the lender had a purse full of coins. A lender is someone who lets others borrow their coins. "Can I borrow ten coins for one week?" asked Ana. Lena could not use those coins while Ana had them, so she waited. "Yes! I ask one extra coin for the week," she said. After one week Ana brought back eleven coins: ten she borrowed and one extra. The extra coin is called interest, the price of borrowing. The next time Ana took two weeks, and she brought back twelve coins, because Lena asks one extra coin for each week of waiting. A good lender says the extra before the borrowing starts.

Borrowing costs extra
111 10 + 1 = 11. Ten were borrowed, and one extra thanks Lena for waiting.
213 Lena asks one extra coin for each week, so 3 weeks is 10 + 3 = 13.
3Interest The extra a lender is paid for waiting is called interest. It is the price of borrowing.
4True While Ana has the coins, Lena cannot use them. The extra thanks Lena for waiting.
51-A, 2-C, 3-B, 4-D A lender lends coins, interest is the extra paid to the lender, each week of waiting adds one extra coin, and a pencil comes back as it was.
6Borrow ten coins for four weeks and pay back fourteen, Borrow ten coins for one week and pay back eleven Fourteen is 4 more than ten, and eleven is 1 more than ten. A ball, a pencil and Gran's loan come back with nothing extra.
74, 3, 2, 5, 1 She needed coins, asked, got them, earned from her baskets and paid back ten plus one extra.
8Two weeks means two extra coins, so she pays back twelve Lena asks one extra coin for each week of waiting. Two weeks is 10 + 2 = 12.
9The lender waits longer, so asks one extra coin for each week A longer wait means more extra coins, so a short wait costs the least.
