Acaterer needs to buy 21 pounds of pasta to cater a wedding. at a local store, 8 pounds of pasta cost $12. how much will the caterer pay for the pasta there?

1. write a ratio for the given information about the cost of pasta

2. would it be more to write an equivalent ratio with 1 pound of pasta as one of the numbers, or with $1 as one of the numbers? explain your reasoning, then write that equivalent ratio.

3. find the answer and explain or show your reasoning.

Step-by-step explanation:

To solve this problem, we need to use the rule of three, which is based on ratios and proportional relationships.

The ratio that shows the cost of pasta is:

Which means that they charge $12 per 8 pounds of pasta.

Now, it would be help if we use the given ratio to apply the rule of three. Looking for a ratio per pound of pasta would be waste of time, and could confuse a lot. So, we just use the given ratio.

If 8 pounds of pasta costs $12, how much would be 21 pounds of pasta?

Therefore, according to the given ration, it would cost $31.50 to get 21 pounds of pasta.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
