Answer:
43 coupons to existing members
Explanation:
Overall, since they provided 6 times as many to potential members as to regular members, 6(potential members) + 1/6 of 6 ( for existing members)=7
301/7=43 existing members
To check our answer, we can do 43 + 43(6 for those potential members) and we get 301! Hope this helps!
