• A. $\$31\text{and}45¢$
• B. $\$21\text{and}55¢$
• C. $\$28\text{and}45¢$
• D. $\$34\text{and}55¢$

Answer 1

The correct option is A $\$31\text{and}45¢$

Given, Amy had the following bills and coins in her piggy bank:
One $20-$ dollar bill $=\$20$
One $1-$ dollar bill $=\$1$
So, total amount money in Amy’s piggy bank $=20+1=\$21$

Stacy added the following bills and coins in Amy’s piggy bank:
Two $5-$ dollar bills $=5+5=\$10$
One quarter $=25¢$
Two dimes $=10+10=20¢$
So, the total amount of money added by Stacy
$=\$10+25¢+20¢$
$=\$10\text{and}45¢$

So, the total amount of money in Amy’s piggy bank
= $21+$10 and 45¢
= $31 and 45¢
