Answer:
The in equality representing the number of can school can collect each day is .
Eddy MS school has to collect at least 500 cans in each day.
Step-by-step explanation:
Number of cans Eddy has = 500
Number of days left = 5
Target to achieve = 3000
Let number of cans which can be collected in each day be 'x'.
Now we know that;
Number of can he has plus number of can which can be collected in each day multiplied with number of days left should be greater than or equal to 3000
Framing in equation form we get;
Hence, The in equality representing the number of can school can collect each day is .
Solving the same we get;
.
Subtracting Both side with 500 using Subtraction property for Inequality we get;
Now Dividing both side by 5 using Division property of Inequality we get;
Hence Eddy MS school has to collect at least 500 cans in each day.

For this case, the first thing we must do is define variables.
We have then:
m: original quantity of merchandise sold (in $)
We then have the following idea:
(original amount) (percent) = new amount
The new amount is the amount that Jacqueline earns for 12% of the commission on sales.
We have then:
Clearing m we have:
Answer:
The equation that solves the problem is:
The amount she sold is:
1) Set up proportions for the ratios:
Cross multiply the fractions:
Divide both sides by 2 to get x by itself.
5 to 2 is equal to 10 to 4.
------------
2) Set up proportions for the ratios:
Cross multiply the fractions:
Divide both sides by 21 to get x by itself:
14 to 21 is equal to 10 to 15.
------------
OPTIONAL:
To make 2) easier to solve, simplify 14 to 21.
Then, continue with the problem as described above:
Cross multiply the fractions:
Divide both sides by 2 to get x by itself.
5 to 2 is equal to 10 to 4.

Answer:
Vincent and Reyna.
Step-by-step explanation:
As z-score indicates that a data point is how many standard deviation above mean, so to find which of three applicant should be offered the job, let us find the z-score for each person using z-score formula.
, where,
= z-score,
= Random sample score,
= Mean,
= Standard deviation.
Therefore, Vincent's score on aptitude test is 1.7 standard deviation above mean.
Therefore, Kaitlyn's score on aptitude test is 0.6 standard deviation above mean.
Therefore, Reyna's score on aptitude test is 1.2 standard deviation above mean.
Since Vincent and Reyna has higher z-scores, therefore, they are further above mean than Kaitlyn. Therefore, Vincent and Reyna should be offered the job.
