Write an expression using the unit cost 0.98 to find the cost of three dozen cookies

11.76 * 3 = $35.28 for 3 dozens of cookies.

Step-by-step explanation:

0.98 cents per cookie

one dozen is 12 cookies

Objective: What is the cost of 3 dozens (Of cookies)

.98 * 12 = 11.76 (Price of one dozen)

11.76 * 3 = $35.28 for 3 dozens of cookies.

11.76 * 3 = x

or

3x = 35.28

35.28

Step-by-step explanation:

We know that the unit cost of cookies is 0.98 and one dozen of something has 12 items in it.

We are supposed to find the total cost of three dozen cookies. If one dozen has 12 cookies then 3 dozen means 3 x 12 = 36 cookies.

So we just need to multiply the number of cookies (in 3 dozen) with its unit cost to get the total cost:

36 x 0.98 = 35.28

Therefore, 3 dozen cookies cost 35.28.
