Question

Someone save my life, like now! I'm confounded on this question.

Mrs. Patton is planning to place a fence around her vegetable garden. The fencing costs $1.75 per yard. She buys f yards of fencing and pays $3.50 in tax. If the total cost is $73.50, how many yards of fencing does she buy?

A.1.75f + 3.50f = 73.50
B. 1.75 + 3.50f = 73.50
C. 1.75f + 3.50 = 73.50
D. 1.75 + 3.50 + 73.50 = f

I pick B, but is that even right?
If its wrong, can someone explain?
Thank you!! :)

Answer 1

C. is the correct answer

Answer 2

Why would it be C?

Answer 3

Actually I would say none of the equations are correct...

The only one that solves for f is incorrect.

C is the proper equation since 1.75*f +3.50 = 73.5 but to solve for how many yards of fencing she buys...

($/yard)(number of yards) + ($ tax) = total $

(number yards) = (total $ - tax $) / ($/yard) ----> units for f is in yards

Answer 4

I think I'm vaguely understanding. Hmm, wonder why I thought it was B.
I seem to go in order of the way the sentence is written,
But thanks for explaining @retirEEd
I appreciate it
