Donny paid $6.60 for a dozen cupcakes for a birthday party. What is the unit cost for each cupcake? (How do you find the unit rate?)
1 dozen = 12 cupcakes
12 cupcakes / $6.60 = 6 ∙ 2 cupcakes / $6 ∙ 1.1 =
2 cupcakes / $1.1 = 2 ∙ 1 cupcake / $ 2 ∙ 0.55 =
1 cupcake / $ 0.55
o.55
To find the unit cost for each cupcake, you need to divide the total cost by the number of cupcakes. In this case, Donny paid $6.60 for a dozen cupcakes.
To find the unit cost for each cupcake, you need to divide the total cost ($6.60) by the number of cupcakes in a dozen, which is 12.
So, you divide $6.60 by 12:
$6.60 ÷ 12 = $0.55
Therefore, the unit cost for each cupcake is $0.55.
