Total number of units = q
Cost of each unit = 100/q + 7
Total cost of q units = q(100/q +7) = 100+7q
To make revenues greater than $8,000
8000<100 +7q
8000-100 < 7q
7900<7q
q>7900/7
q>1128.58
q>1129 units
Therefore, the minimum number of units sold must be greater than 1129 units.
An equation that correctly represent this relationship if x represents the number of pounds of fertilizer and y the number of ounces of weed killer is 0.5x + 3.5y = 70
<u>Solution:</u>
Given that, Bill spent 70 on fertilizer and weed killer for his lawn
Each pound of fertilizer cost 50 cents and each once of weed killer cost 3.50
We have to write an equation, if x represents the number of pounds of fertilizer and y the number of ounces of weed killer.
Now,<em> total amount = amount for fertilizers + amount for weed killers.</em>
Total amount = number of pounds of fertilizers x cost per pound + number of ounces of weed killer x cost per ounce.
![\begin{array}{l}{\rightarrow 70=x \times 0.50+y \times 3.50} \\\\ {\rightarrow 0.5 x+3.5 y=70}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7B%5Crightarrow%2070%3Dx%20%5Ctimes%200.50%2By%20%5Ctimes%203.50%7D%20%5C%5C%5C%5C%20%7B%5Crightarrow%200.5%20x%2B3.5%20y%3D70%7D%5Cend%7Barray%7D)
Hence, the equation is 0.5x + 3.5y = 70
Answer:
$131.85
Step-by-step explanation:
First, we need to find the net price (after discount and tax) It's a 15% discount, so just find 85% (100-15=85) of the original price. You'll get $373.15.
For tax, multiply by 1.06, since it's a 6% tax (1+.06). You'll get $395.539.
You're paying over 3 months time, so to find payment each month just divide by 3.
395.539/3 = 131.8463333
Round to 131.85
Your answer is $131.85 dollars per month
