Jackson's bakery sold one customer 8 dozen chocolate cookies and 9 dozen oatmeal cookies for $111. the bakery also sold another customer 2 dozen chocolate cookies and 9 dozen oatmeal cookies for $75. how much do the cookies cost?

a dozen chocolate cookies cost $ and a dozen oatmeal cookies cost $

$6; $7

Step-by-step explanation:

Since they both had 9 dozen oatmeal cookies, we can do 111-75 to see that the difference in money spent is 36.

Then divide that by 6 to see that each dozen of chocolate is $6.

Now we take 111-48 to get 63. We get the 48 from how much the first customer spent on chocolate cookies.

Divide 63 by 9 since thats how many dozens of oatmeal cookies were bought and you get $7.

Hope this helps
