Erykah has 6 less than 3 times the number of stamps in her collection that Chris has in his. Let r equal the number of stamps Ch
S_A_V [24]

Answer:

Option C is correct.

The expression represents the number of stamps Erykah has : 3r -6

Step-by-step explanation:

as per the given condition: Erykah has 6 less than 3 times the number of stamps in her collection that Chris has in his.

"3 times the number of stamps Chris has" means 3r

"6 less than 3 times number of stamps Chris has" which means subtract 6 from 3r i,e 3r -6

therefore, the expression 3r -6 represents the number of stamps Erykah has.
