Mr. Walker, the contest sponsor, bought toy Wheels in a package of six dozen for $81. what was the unit cost of each wheel?

1.125

Step-by-step explanation:

the unit cost is how much it cost per wheel

dozen is 12

so 12 times 6 is 72

so then you do 81/72 to get your answer

and you are probably wondering how i got the divison from was because i'm supposed to divide to find a unit cost.

the 81 was the total for the 72 packages of toy wheels
