Meadow Academy's spring festival is coming up, and Ms. Rivera is in charge of ordering the butterfly kits again. She knows she ordered 6 cases of butterfly kits last year but can't remember how many kits come in a case. When she checks the records, Ms. Rivera finds that the school used 417 of the butterfly kits last year and had 63 left over after the festival. How many butterfly kits come in each case?

butterfly kits

Let's assume there are x butterfly kits in each case.

Last year, the school used 417 kits and had 63 left over, so the total number of butterfly kits ordered was 417 + 63 = 480.
Since each case contains x kits, the total number of cases ordered is 480 / x.
Ms. Rivera knows she ordered 6 cases, so we can set up the equation 480 / x = 6.
To solve for x, we can multiply both sides of the equation by x, which gives us 480 = 6x.
Dividing both sides of the equation by 6, we find that x = 80.
Therefore, there are 80 butterfly kits in each case.
