Given that Jenna and Callie collect stamps. Jenna has 20 less than twice the number of stamps that Callie has. Now we need to find about which expression represents the number of stamps that Jenna has.

Let number of stamps collected by Jenna = J

Let number of stamps collected by Callie = C


"twice the number of stamps that Callie has" means 2 times C o just 2C

Now "Jenna has 20 less than twice the number of stamps that Callie has" means

J=2C-20


So the final expression is J=2C-20.
