First, calculate how many slices of cake there were before they were eaten.

If each cake has 12 slices and 6 cakes were bought then we multiply 6 by 12.

6 * 12 = 72

Now we know 72 slices was start before being consumed.

Now we want to know how many was eaten. We just find difference between 72 and the remaining slices of cake. Which is 7.

72 - 7 = 65

So, 65 slices of cake was eaten.
The correct answer is the letter C. This is the correct answer because, you multiply the number of cakes to how many slices each cake has. So it would be: 6x12. That equals 72. Then you would need to subtract the 72 to the number of the remaining slices. The remaining slices were 7. Next you do: 72 - 7. The answer to that is 65. So there was 65 slices of cake eaten at the dinner. Hope this helps! :) Pls mark me as the brainliest!!!
