Answer:
C
Step-by-step explanation:
Answer: $4.31
Step-by-step explanation:
$3.99(0.08) = $0.3192 which will round up to $0.32
$3.99 + $0.32 = $4.31
Total money=$120
on shirt=$25.65
on socks=$7.98
on a cd=$16.23
on snack=$4.58
so total money left=total money-total money spent
=$120-($25.65+$7.98+$16.23+$4.58)
=$120-$54.44
so total money left=$65.56
Using the permutation formula, the <u>number of different options for the top three finishers</u> is given as follows:
The order in which the players are chosen is important, as A, B, C is a different outcome than C,B,A for example, hence the <em>permutation formula</em> is used to solve this question.
<h3>What is the permutation formula?</h3>
The number of possible permutations of x elements from a set of n elements is given by:
In this problem, 3 students will be chosen from a set of 14, hence the number of ways is:

Answer:
2y + 8x = 16
Step-by-step explanation:
You're trying to get this into ax + by = c
So you want to isolate the constant (16)
4y + 5x = 2y - 3x + 16
-2y -2y
2y + 5x = -3x + 16
+3x +3x
So, 2y + 8x = 16 is your answer.
