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.

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.
