The function representing the percentage of work that remains in terms of the number of weeks since the project started is y =? â ? x.

Answer 1

Answer:

y = .25x

Step-by-step explanation:

In equations, percentages will most often have to be represented with a decimal equivalency.  If .75 of the work is done, then 75% of the work has been done.  The .75 means 75% of the work has been done.

Percentages are based on 100%; you cannot have more than 100% of something.  If 75% (.75) of the work has been done, then 25% (.25) remains.  Therefore, the equation that represents the percentae of work that remains is

y = .25x
