Kim bought a total of 48 cookies. Each cookie costs $.55, including tax. Of the cookies she bought, 3/8 were lemon cookies. What was the total cost of only the lemon cookies?

(3/8) * 48 * 0.55 = $_______

To find the total cost of only the lemon cookies, we first need to determine how many lemon cookies Kim bought.

We're given that Kim bought a total of 48 cookies, and 3/8 of them were lemon cookies. To find out the number of lemon cookies, we multiply the total number of cookies by the fraction representing the proportion of lemon cookies:

Number of lemon cookies = (3/8) * 48

To calculate this, we multiply the numerator (3) by 48 and divide the result by the denominator (8):

Number of lemon cookies = (3 * 48) / 8 = 144 / 8 = 18

So Kim bought 18 lemon cookies.

Next, we need to find the total cost of only the lemon cookies. We're given that each cookie costs $0.55, including tax.

To find the total cost of the lemon cookies, we multiply the cost of one lemon cookie by the number of lemon cookies:

Total cost of lemon cookies = Cost per lemon cookie * Number of lemon cookies

Total cost of lemon cookies = $0.55 * 18 = $9.90

Therefore, the total cost of only the lemon cookies is $9.90.
