The amount of time it takes Heather to cook dinner is directly proportional to the number of ingredients involved. If it takes her t minutes to cook dinner when there are n ingredients involved how long does it take her to cook dinner when there are 15 ingredients involved?

15 minutes!

Since the ratio is 1 : 1, for every one ingredient it will take her one minute. 15 ingredients = 15 minutes.

Hope that helped!

:D®

P.S. I wonder what she's cooking.

Answer:


(15t)/(n)\text{ minutes}

Explanation:

Given,

Time taken to cook dinner with n ingredients = t minutes.

i.e. n ingredients = t minutes,

⇒ 1 ingredient =
(t)/(n) minutes,

⇒ 15 ingredients =
(15t)/(n) minutes,

Hence, it will take
(15t)/(n) minutes to cook dinner when there are 15 ingredients involved.
