4.Phillip is having a cookout. Phillip wants to buy an equal number of hot dogs and hamburgers. What is the smallest number of packages of each that Phillip could buy so that there are no leftover hot dogs, hamburgers, buns, or rolls?

4.Hot dogs cost $3.29 per package, hamburger patties cost $3.79 perpackage, and buns and rolls cost $2.29 per package. What will it cost Phillip to buy hot dogs, hamburgers, buns, and rolls for his cookout?
The digits 0 through 8 have been classified with the letters A,B and C. How would you classify the digit 9? Why?
A 1 4 7 (9?)
B 2 5
C 0 3 6 8
Is my answer right?

1 and 2 are correct.
4. If there are equal numbers of hamburgers and hot dogs, you have to have 3 packages of hot dogs for every 5 packages of hamburgers. If they are 12 and 20, respectively, then the buns are 15 and 15, respectively.
Are you sure you don't have a typo for the last question? If each number increased by 3, then the below would apply.
A 1 4 7
B 2 5 8
c 0 3 6 (9)
