Question

Describe a real world situation that can be modeled by the equation y = 1/20x. be sure to describe what each variable represents.

Answer 1

y = 1/20x
Multiply both sides by 20

20y = 20(1/20) x
20y = (20/20)x
20y = x

Let's say Milk costs $1
And let's say a coat costs $20.

Then 20(the costs of milk) = The cost of a coat
y = cost of milk
x = cost of a coat

y = (one twentieth) x
