Answer: first option
Step-by-step explanation:
Direct variation equation has the following form:

Where "k" is the constant of variation.
In direct variation when the variable "x" increases, the variable "y" increases by the same factor and when the variable "x" decreases, the variable "y" decreases by the same factor.
Inverse variation equation has the form:

Where "k" is the constant of variation.
In inverse variation when the variable "x" increases, the variable "y" decreases by the same factor and when and when the variable "x" decreases, the variable "y" increases by the same factor.
Given the equation:

You can observe that "r" varies directly with "l" and inversely with "p" and "t"
Try this:

If it is possible, modify result to form more compact.
Answer:
13 weeks
Step-by-step explanation:
multiply $30 by 13 weeks you get $390 add the $210 and get $600
Answer:
Hey, ill do like 2 and you can do the rest
percent decrease or change is
new-old over old
So like #1
1) 60 is old, 48 is new
so 48-60=-12
now over old which is 60
-12/60
-1/5
20 percent decrease
2) 180 is old, 108 is new
108-180=-72
-72/180
40 percent decrease
