Monica made 1 red bracelet and 4 blue bracelets. She made twice as many black bracelets as red bracelets. She told her friend she made 7 bracelets.

Was Monica's calculation reasonable?

A.
Yes, it is reasonable because 1 + 4 + 2 = 7.

B.
No, it is not reasonable because 1 + 4 + 5 = 10.

C.
No, it is not reasonable because 1 + 4 + 8 = 13.
