Select the equation that most accurately depicts the word problem.

a 3-pound tub of butter at n dollars per pound costs $3.85.

3n = 3.85
3 - n = 3.85
3 + n = 3.85
= 3.85

Step-by-step explanation:

Given : A 3-pound tub of butter at n dollars per pound costs $3.85.

i.e. cost one pound butter is given to be 'n'.

Then the cost one pound butter must be expressed by '3n'. [By unitary method]

Also, it is given that the cost of 3 pound tub of butter is $3.85.

Then, the equation that most accurately depicts the word problem will be :

Hence, the correct answer is .
