1 answer:
Answer:
$0.10
Step-by-step explanation:
We can divide the total amount ($12) by price of each avocado ($0.85) to get the number of avocados possible. That is:
So, the fractional amount (decimal) is not possible, so Raul can get 14 avocados.
<em>How much does 14 avocados cost?</em>
<em>14 * 0.85 = $11.90</em>
<em />
The rest, he gets as change and can't buy another full avocado. The change is:
$12 - $11.90 = $0.10

Answer: c. 8!
Step-by-step explanation:
We know , that if we line up n things , then the total number of ways to arrange n things in a line is given by :-
( in words :- n factorial)
Therefore , the number of ways 8 cars can be lined up at a toll booth would be 8! .
Hence, the correct answer is c. 8! .
Alternatively , we also use multiplicative principle,
If we line up 8 cars , first we fix one car , then the number of choices for the next place will be 7 , after that we fix second car ,then the number of choices for the next place will be 6 , and so on..
So , the total number of ways to line up 8 cars = 8 x 7 x 6 x 5 x 4 x 3 x 2 x1 = 8!
Hence, the correct answer is c. 8! .
