Answer:
1320 ways
Step-by-step explanation:
Here we have a situation where 3 ribbons will be awarded to 3 of the 12 contestants. We can use the permutation formula, because the order of awarding the ribbons matters.
The permutation formula is:

n = 12
k = 3
Now that we have our variables, let's plug them into the formula.



So there are 1320 different ways that the contestants will be awarded.

Now I dont know if the three in the front is supposed to be in there or if its numbering the problem so I solved it with and without it. The first ones with and the second one without.
=8 3/4
(Decimal: 8.75)
=5 3/4
(Decimal: 5.75)
I think that the answer is d
$6.05 because 10.09 × 0.6 is 6.054, round down because the last number is less than 5, and you have 6.05.
