Answer:

<em>The table shows a proportional relationship: YES</em>

<em>The constant of proportionality is k=7</em>

<em>y = 7x</em>

Step-by-step explanation:

<u>Proportions</u>

A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:

y = kx

Where k is the constant of proportionality. It can be calculated by solving the equation for k:

\displaystyle k=\frac{y}{x}

We are given a table with 4 pairs of values. If the relationship between the variables is proportional, then the ratio y/x should be constant.

Let's verify some points:

\displaystyle k=\frac{63}{9}=7

\displaystyle k=\frac{28}{4}=7

\displaystyle k=\frac{14}{2}=7

\displaystyle k=\frac{77}{11}=7

Since all the ratios are equal,

The table shows a proportional relationship: YES

The constant of proportionality is k=7

The equation for the relationship is

y = 7x

Alice purchased 4 1⁄2 kilograms of olive oil for $27. What is the price per kilogram?
Ede4ka [16]
<h3>Answer: 6 dollars per kilogram</h3>

=====================================================

Explanation:

The mixed number 4 & 1/2 converts to the decimal form 4.5

The unit price is 27/(4.5) = 6 dollars per kilogram

------

If you wanted, you can think of it like this ratio

4.5 kg : 27 dollars

Dividing both parts of that ratio by 4.5 will lead to

1 kg : 6 dollars
