a.2c + 20
b.2c - 20
c.20 - 2c
d.20 + 2c

Answer 1

the correct answer is 2c-20 because its being multiplied by the amount she has and then subtracted by the total amount

Answer 2

We have been given that C represents number of stamps collected by Callie.

Therefore, twice the number of stamps that Callie collects = 2C

Now, it has been given that Jenna has 20 less than twice the number of stamps that Callie has.

Therefore, the number of stamps that Jenna has is given by

`2C-20`

Therefore, the expression 2C - 20 represents the number of stamps that Jenna has.

b is the correct option.
