Answer:

I would need to see the options

Step-by-step explanation:

But here is how one could look. g=3+(m/p). In this equation g is the amount of guests she can brin, m the amount of money she has and p the price to bring in guests(after the third shown be the 3+...).

Answer:

5.) Proportionality is 3/1 or 3 simplified

• b x 3 = p
• b= boxes
• p= pens in box

6.) Proportionality is 1/6

• m ÷ 6 = p
• m = muffins
• p= pack(s) of muffins

Step-by-step explanation:

You would take the first column (or in this case row (pens and packs) and place the 2nd row under it in fraction form.

• 5.) 3/1 = 3
• 6.) 1/6 = 1/6

That would be your proportion

Then you would (in place of numbers) use letters to symbolize in the equation

• 5.) p = pens: b= boxes
• 6.) m= muffins; p= pack

Then create an equation to figure out how to get the correct numbers.

• 1 box holds 3 pens so:
• 5.) b x 3 = p
• Check: 2 boxes x 3 pens per box = 6 pens (check table) Correct!
• 6 muffins in 1 pack so:
• 6.) m ÷ 6 = p
• 12 muffins ÷  6 muffins in per box = 2 packs (check table) Correct!
