Answer:
Either of;
3 Baseball cards come in packages of 8 and 4 Baseball cards come in packages of 12
or
He bought 6 Baseball cards come in packages of 8 and 2 Baseball cards come in packages of 12.
Step-by-step explanation:
On the condition that he bought some of each type for a total of 72 baseball cards, then the numbers bought must be factors of 72. To start, the lowest common multiple of 8 and 12 is 24. 24 divided by 8 and 12 gives 3 and 2 respectively. 24 out of 72 leaves a remainder of 48. 48 divided by 8 and 12 gives 6 and 4 respectively.
As such, if Brighton bought some of each type for a total of 72 baseball cards then he either bought 3 Baseball cards come in packages of 8 and 4 Baseball cards come in packages of 12 or he bought 6 Baseball cards come in packages of 8 and 2 Baseball cards come in packages of 12.
