Using combination and permutation we found out that there are 30240 ways to make varieties of pizza with 3 toppings.
Given 10 toppings
10C3 =10!/3! 7! =120
10P5 =10!/5! =30240 ways
A permutation is a process of placing objects or numbers in order. Combining is the ability to select an object or number from a group of objects or collections such that the order of the objects does not matter.
In mathematics, a combination is the selection of elements from a set with different members, so the order of selection does not matter.

What you would do is simply plug in 8 where y is and solve. 5(8)=3478-3c -Times 5 by 8 40=3478-3c -Add 3c to the opposite side of the equal sign 40+3c=3478 -Subtract 40 from the opposite side of the equal sign 3c=3438 -Divide equation by 3 c=1146
