2.5 (x-7) + 0.5=12.5.

"I bought a cookbook for $7. If I had $2.5 more, I could have bought another book for $12.50".

Assuming that Alex had $x to begin with, identify the errors in Alex's description?

Answer Choices (there can be more than one)

Alex must say "2.5 times the money that was left with" instead of "$2.5 more".

Alex must say $2.5 less instead of $2.5 more.

Alex cannot buy a book for $7 if it costs $12.50.

Alex has missed the 0.5 term in his description.
