Karl bought five folders from Pay-A-Lot at a cost of $\$2.50$ each. Pay-A-Lot had a $20\%$ -off sale the following day. How much could Karl have saved on the purchase by waiting a day?

$\$ 1.00$

$\$ 2.00$

解答：

Karl 为文件夹支付了 $5\cdot\$2.50=\$12.50$ 。

$20\%$ 的 $\$12.50$ 折扣会省下 $0.20\cdot12.50=2.50$ 美元。

所以正确答案是 C。

Karl paid $5\cdot\$2.50=\$12.50$ for the folders.

A $20\%$ discount on $\$12.50$ would save $0.20\cdot12.50=2.50$ dollars.

Thus, C is the correct answer.
