Answer:

Store A and it would cost $32.40 (answer choice A)

Step-by-step explanation:

Let's start by studying how much she would pay for a single balloon on each store:

In store A: (5 balloons for $6) then per each balloon: $6/5 = $1.2 per balloon.

In store BA: (13 balloons for $16.25) then per each balloon: $16.25/13 = $1.25 per balloon.

This shows us that the better price is in store A if she wants to pay as little as possible. Now, at that price, if she wants to buy 27 balloons, she will be paying (27 times $1.2): 27 * $1.2 = $32.40

A - g(x) = |x-5|+5 <br> B - g(x) = |x-5| <br> C - g(x) = |x|+5 <br> D - g(x) = |x+5|+5
n200080 [17]

Answer:

g(x) =  |x|  + 5

Step-by-step explanation:

Since both the original and transformed graph have the same x value for their vertex, there was no horizontal shift. However the vertex shifted up. Specifically it shifted up 5 units. Therefore:

g(x) = f(x) + 5

The plus 5 performs a translation up 5 units. Plugging in for f(x) it can be seen that:

g(x) =  |x|  + 5

There is 7/8 quarts of orange juice. Mrs. Mathewson would like to serve her guests 3/16 quarts orange juice. How many guests can
kotegsom [21]

Answer:

4\frac{2}{3} guests.

Step-by-step explanation:

We have been given that there are 7/8 quarts of orange juice. Mrs. Mathewson would like to serve her guests 3/16 quarts orange juice.

To find the number of guests Mrs. Mathewson can serve with 7/8 quarts of juice, we will divide 7/8 by 3/16 as:

\text{Number of guests Mrs. Mathewson can serve}=\frac{7}{8}\div\frac{3}{16}

Convert to multiplication problem by flipping the 2nd fraction:

\text{Number of guests Mrs. Mathewson can serve}=\frac{7}{8}\times\frac{16}{3}

\text{Number of guests Mrs. Mathewson can serve}=\frac{7}{1}\times\frac{2}{3}

\text{Number of guests Mrs. Mathewson can serve}=\frac{14}{3}

\text{Number of guests Mrs. Mathewson can serve}=4\frac{2}{3}

Therefore, Mrs. Mathewson can serve orange juice to 4\frac{2}{3} guests.
