lance made 10 dozen cookies. He made 25 percent chocolate chip, 25 percent peanut butter, and the remaining 50 percent oatmeal raisin. How many of each type of cookie did he make?

0.25(10 * 12) = ?

To find out how many cookies of each type Lance made, we first need to determine the total number of cookies.

Since Lance made 10 dozen cookies, we need to convert that to a total number of cookies. There are 12 cookies in one dozen. So, 10 dozen cookies would be 10 x 12 = 120 cookies.

Next, let's find out how many chocolate chip cookies he made. 25% of the cookies were chocolate chip, so we can calculate it by multiplying the total number of cookies by 25% (or 0.25):

Chocolate chip cookies = 120 x 0.25 = 30 cookies.

Similarly, 25% of the cookies were peanut butter cookies, so we can find the number of peanut butter cookies using the same calculation:

Peanut butter cookies = 120 x 0.25 = 30 cookies.

Finally, the remaining 50% of the cookies were oatmeal raisin cookies:

Oatmeal raisin cookies = 120 - (30 + 30) = 60 cookies.

So, Lance made 30 chocolate chip cookies, 30 peanut butter cookies, and 60 oatmeal raisin cookies.
