An ice cream shop has 15 different toppings for sundaes, and it is running a special for 3 free toppings. How many 3-topping sundaes can be made, assuming all 3 toppings chosen are different?

455

Step-by-step explanation:

This is a combination problem: we need to create groups of 3 elements from the pool of 15 options, and the order of the elements in the group doesn't matter.

So, to solve the problem, we need to find the combination of 15 choose 3:

C(15,3) = 15! / (3! * 12!) = (15*14*13)/(3*2) = 455

We can make 455 different 3-topping sundaes.

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
