Use the scenario and elimination by multiplication to answer the question.

6 0

Answer:
C
Explanation:
You could solve this in the elimination way that I have been done in here.

I use Jason as an example that he paid $11.84 for 5t ( tacos ) + 1q ( quesadilla )
Therefore we could do the elimination if the taco cost 3.45 x 5 = 17.25, would be over the cost.

-> Cross B answer

Then we take 1.57 x 5 = 7.85. 11.84 - 7.85 = 3.99, which it is not 3.39 => Cross D answer.

Therefore the cost of tacos need to be 1.69 because there have been a repetition in both A& C

1.69 x 5 = 8.45. $11.84 - 8.45 = $3.39 for quesadillas.

Which it proves for the answer is C

Hope I have helping you on this question

How many ways can first, second, and third place be assigned?At a gymnastics meet, twenty gymnasts compete for first, second, an

S_A_V [24]

<h2>Answer:</h2>

The total number of ways can first, second and third place can be assigned are:

6840

<h2>Step-by-step explanation:</h2>

The total number of people that compete are: 20

Out of these 20 people we have to chose 3 people and also arrange them according to their ranks.

We know that when we have to choose and arrange r items out of total n items then we need to use the method of permutation.

Hence, the formula is given by:

$n_P_r=\dfrac{n!}{(n-r)!}$

Here we have:

n=20 and r=3

Hence, the number of ways first, second and third place can be assigned are:

${20}_P_3=\dfrac{20!}{(20-3)!}\\\\\\{20}_P_3=\dfrac{20!}{17!}\\\\\\{20}_P_3=\dfrac{20\times 19\times 18\times 17!}{17!}\\\\\\{20}_P_3=20\times 19\times 18\\\\\\{20}_P_3=6840$
