Ezra and Sophie are planning a picnic for a group of friends.
They have $100 to spend.
They will buy one large salad for $28.50.
They will also buy some sandwiches for $4.85 each.
Ezra thinks they can buy at least 20 sandwiches, but Sophie thinks they can buy no more than 14 sandwiches.
Which estimation strategy will show who is correct?
A.
Each sandwich costs about $5, so 20 sandwiches cost about $100, so Ezra is right.
B.
Each sandwich costs about $5, so 14 sandwiches cost about $70, so Sophie is right.
C.
Each sandwich costs about $4, so 20 sandwiches cost about $80, so Ezra is right.
D.
Each sandwich costs about $4, so 14 sandwiches cost about $55, so Sophie is right.
