There are 3 paperclip chains. Chain A is 50 inches long, Chain B is 4 1/4 feet long. Chain C is 1 yard long. Order the chains from the longest length to the shortest length.

• Chain A, Chain B, Chain C

• Chain B, Chain C, Chain A

• Chain C, Chain B, Chain A

• Chain B, Chain A, Chain C

Answer explanation

To compare lengths, convert all chains to inches: Chain A = 50 inches, Chain B = 4.25 feet = 51 inches, Chain C = 1 yard = 36 inches. Thus, the order from longest to shortest is Chain B, Chain A, Chain C.

• $5.11

• $4.89

• $6.21

• $7.00

Answer explanation

Maria spent a total of 5.34 + 9.55 = 14.89. She paid with a 20 bill, so her change is 20 - 14.89 = 5.11. Therefore, she would get $5.11 back.

• $17.54

• $16.54

• $18.54

• $15.54
