Word problem
mark and melinda collect baseball caps. mark has 7 more than melinda.
togheter they have 115 caps. how many baseball caps does each of them have?
i got: melinda has 54 mark has 61
is that right?
i have 2 more i cant figure out:
1) in a pet store the number of dogs is more than 3 times the number cats. if the pet store has 21 dogs how many cats does it have?
2) in the pet store the number of birds is 10 less than twice the number of rabbits, if the pet store has 56 birds, how many birds does it have?

MATH 
Olivia,
1) yes I think is right
2) 21x3=63
3) Not quite sure it doesn't make any sense 
MATH 
marko,
for question 1 is it 9 cats

MATH 
Ms. Sue,
The first one is right.
1) The store has less than 7 cats.
2) 56  10 = 46
46/2 = 23 
MATH 
marko,
so question 1
is 7 cats
i don't follow how you got 7?
question 2 is 23 rabbits 
MATH 
Ms. Sue,
21 dogs
21 = 3c
Solve for c 
MATH 
marko,
3x 7 = 21
so c = 7
i get it
thanks 
MATH
