Question below..................
A store received 620 containers of milk to be sold by March 1. Each container cost
the store $0.78 and sold for $1.56. The store signed a contract with the distributor in
which the distributor agreed to a $0.40 refund for every container not sold by March
1. If 430 containers were sold by March 1, how much profit did the store make?
9514 1404 393
Answer:
$263.20
Step-by-step explanation:
The number not sold was ...
620 -430 = 190
The cost for a container not sold was ...
$0.78 -0.40 = $0.38
__
The cost of containers sold was ...
$0.78 × 430 = $335.40
The cost of containers not sold was ...
$0.38 × 190 = $72.20
The total cost for the 620 containers of milk was ...
$335.40 +72.20 = $407.60
The total revenue from the 430 containers sold was ...
$1.56 × 430 = $670.80
Then the profit was ...
profit = revenue - cost
profit = $670.80 -407.60 = $263.20
_____
Additional comment
The calculation can be simplified to ...
$1.16 × (number sold) - $0.38 × (number bought)
Rocco loves making spaghetti with his grandmother. They make homemade tomato sauce by adding pureed tomatoes, sugar, salt, olive oil, and water. He notices that after he stops stirring, he sees a greasy film at the top of the red liquid. What does this tell you about his sauce mixture?
Oil floats on water because it is less dense I believe. So that would be the oil on top of the sauce(the oil is on top because of the water that was also added).
A line passes through the point (−3,−10) , and it’s perpendicular to the line y=0 . Find an equation for this line.
Answer:
Step-by-step explanation:
y = 0 is actually the x axis.
All the points on the line you want have an x value of - 3
-3,-10 is actually one of those points
The equation you want is x = - 3

. If there are 200 bacteria at the end of the first day, how many bacteria willthere be after 2 days,
after 4 days, after 5 days, after 6 days and after 7days if the bacteria triple in number every day?
Answer:
See belowStep-by-step explanation:
The first part solved only. The second part is incomplete.
Using the information we build the equation for salary calculation:
S(x) = (x - 2014)*6000 + 250000, where S is the annual salary at year x, provided x > 2014Use the equation and work out salary:
S(2015) = 1*6000 + 250000 = 256000S(2016) = 2*6000 + 250000 = 262000S(2018) = 4*6000 + 250000 = 274000S(2020) = 6*6000 + 250000 = 286000S(2021) = 7*6000 + 250000 = 292000Summary

Eric will run at least 35 miles this week. So far, he has run 18 miles. What are the possible numbers of additional miles he will run?
Use t for the number of additional miles he will run.
Write your answer as an inequality solved for t.
Answer:
18 + t ≥ 35
possibly 17 miles or more
Step-by-step explanation:
18 + t = 35 --> minus 18 on both sides
t = 17
18 + t ≥ 35

the coeffient of variation, expressed as a percent, is used to describe the standard deviation relative to the mean. It allows us to compare variability of data sets with different measurement units and is calculated as coefficient of variation =100(s/x) Find the coefficient of variation for the following sample weights in pounds 130,127,186,105,197,153,172,150,116,125
The required coefficient of variation 23.44.
What is sample space?
A sample space is a set of potential results from a random experiment. The letter "S" is used to denote the sample space.
Given that,
The coefficient of variation for the sample,
CV = 100(s/x),
Where s is the standard deviation and x is the mean,
According to the provided formula,
The mean weight is 143.5 pounds,
And the standard deviation is 33.65 pounds.
Thus, after entering those values:
CV = 100 * (33.65/143.5)
CV ≈ 23.44
Therefore, for the sample weights in pounds that is given, the coefficient of variation is roughly 23.44.

Mary borrowed $4,500 to help
pay for college. If the bank
charges a 5.5% annual interest
rate, how much interest will
Mary pay after 4 1/2 years?
Answer:
1113.75
Step-by-step explanation:
The formula for simple interest is as follows: Simple interest = principal balance x interest rate x term of the loan
P=4500
i= 0.055
t=4.5
multiplying them together we get
1113.75
The reason that this is simple interest is because compound interest increases over time as an exponential

Kristen babysits 38 hours a week for $6.80 per hour. She earns an additional $224.00 in tips . How much did she make in 1 week?
Answer:
$502.40
Step-by-step explanation:
Kristen works 38 hours for $6.80 per hour.
We multiply her pay and the hours she worked:
38 × 6.8 = 258.4
Thus, she makes $258.40/week
Now we add her tips, which would be the equation 258.4 + 224
258.4 + 224 = 502.4
So, she made $502.40 in 1 week
