Carol, Gideon, and Jose each eat two cookies each day, while Mary eats one cookie each day. There are enough cookies in a jar to last 24 days. How many days will the cookies last if Mary also ate an additional cookie each day?

Answer for sheet # 10

21 days

Total number of cookies in the jar= 168
(6 +1) x 24 days = 168 cookies in the jar

168 cookies /8 cookies/day = 21 days
