Answer:
Price will you offer it after the discount is $332.64 .
Step-by-step explanation:
As given
An article sells for $415.80.
You wish to discount it by 20%.
20% is written in the decimal form .
= 0.20
Discount price = 0.20 × Article cost
= 0.20 × 415.80
= $ 83.16
Price offer after the discount = Selling price of the article - Discount price
= $415.80 - $ 83.16
= $ 332.64
Therefore price will you offer it after the discount is $332.64 .

Answer:
a. 125 – 7d
Step-by-step explanation:
Let d be the number of days.
<u>Given the following data;</u>
Total distance (month) = 125 miles
Distance covered per day = 7 miles
To determine how many miles he has left to run after running for "d" days, this mathematical expression can be used;
Total distance - distance covered per day = number of miles remaining
Consider the function 
, which has derivative 
.
The linear approximation of
for some value 
within a neighborhood of 
is given by
Let
. Then 
can be estimated to be
![\sqrt[3]{63.97}\approx4-\dfrac{0.03}{48}=3.999375](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B63.97%7D%5Capprox4-%5Cdfrac%7B0.03%7D%7B48%7D%3D3.999375)
Since
for 
, it follows that must be strictly increasing over that part of its domain, which means the linear approximation lies strictly above the function . This means the estimated value is an overestimation.
Indeed, the actual value is closer to the number 3.999374902...
