Sales this year are off by 20% in the coat department. last year in july they sold 415 coats. how many coats did they sell this year in july?

 332

Step-by-step explanation:

Given : The percent of sales off this year in July= 20%

Which can be written as 0.20

The sales of coat in last year in July= 415

Let x be the number of coats they sell in this year in July , then the decrease in sales :  

We have the following equation:-

Hence, the number of coats , they sell this year in July =332 .

the slope of the first function is -3. (3/1)

the slope of the second function is 1. (13-10/6-3).

since |-3| is greater than |1|, the function with the steepest slope is the first.
