l his savings
plan to determine how many more months of saving it will take to reach his goal. In the equation Damon created, x represents the number of
months since last week and y represents the total amount he's saved for the vacation Review his work, and select the true statement.
Step 1:
y = 500 + 400x

Answer:

<h3>He needs 5 more months of savings for him to reach his goal. </h3>

Explanation:

Given the equation that models Damon's saving plan as y = 500 + 400x  where x represents the number of  months since last week and y represents the total amount he's saved for the vacation. Since he estimates that he'll need about $2,500 for the trip, therefore y = $2,500.

In order to determine how many more months of saving (x) it will take to reach his goal, the following steps must be taken by Damon (Damon true statements)

Step 1:

y = 500 + 400x

Step 2: Subtract 500 from both sides

y - 500 = 500 + 400x - 500

y-500 = 400x

Step 3: Substitute y = $2500 into the resulting equation and solve for x

400x  = 2500-500

Step 4:  Take the difference of the value at the right hand side of the equation

400x = 2000

Step 5: Divide both sides by the coefficient of x (i.e 400)

\frac{400x}{400}= \frac{2000}{400}

Step 6: Get the value of x

x = 5

Alja [10]

Answer:

As Mary is a newly-hired police officer, she observes two fellow officers removing drugs from the evidence room. Mary's values include devotion to loyalty, so Mary is inclined to protect her fellow officers. At the same time, Mary also believes in upholding the law. Mary's decision to report the crime had negative effects for the two officers involved, and for Mary personally. however, the rest of the community has benefited from the removal of corrupt police officers. A(n) utilitarian viewpoint would find this outcome to be ethical.

Explanation:

As we can see that Mary has taken the decision which is ethical from the utilitarian viewpoint. In utilitarian viewpoint, we decide and make decisions on the basis of the outcomes, We put efforts and decide whats going to be the likely outcome and results of our decisions. We mainly see the consequences and then proceed to make the decision. Moreover, in this viewpoint, moral values, ethics and justice is also given the main weightage. we focus not only our personal benefits but we see the benefits of large number of people. If we like something and other people do not like it then we will not make that decision. If two people in a group want to go to China for summer holidays, and five people are preferring going to London, then our decision will be going to London because in this case we can benefit more number of people. Same is the case here, Mary wants to proceed while thinking the benefits of its community.
