Hello from MrBillDoesMath!
Answer:
This is a puzzling one! The answer is indeed -3/4 but I was unable to prove it using mathematics appropriate to the "middle school" level. Sorry I couldn't be more helpful.
(To prove it I generated the first few terms of its Laurent series, a Calculus topic. The first few terms are -(3/4) + (41/64x) + and as x approaches minus infinity the term with "x" in the denominator goes to zero, leaving the constant value -3/4 as the answer. )
Thank you,
MrB
Find the perimeter of the yard ( the distance around the yard).
A rectangle has two sides of each dimension.
The perimeter is 20 + 20 + 45 + 45 = 130 feet.
Now multiply the total feet by the cost per foot:
130 feet x 25 per foot = $3,250 total.
Answer:
Step-by-step explanation:

use a calculator fo find the value
$0.85 * 4 = $3.40
$6.40 - $3.40 = $300
Brussel sprouts per pound = $300 / 4
= $0.75
