The total cost, c, in dollars, of b bottles of water is c = 1.1b.

What is the constant of proportionality?

Enter your answer as a decimal in the box.

I need as a decimal, not fraction, also please try to explain how you got the answer

Since as b increases by 1, c increases by 1.1, the constant of proportionality is [tex] \frac{1.1}{1} [/tex] or 1.1

Answer: 1.1


Step-by-step explanation:

Given expression : c = 1.1b, where c= total cost of b bottles of water.

Two variables are proportional if there is always a constant ratio between them, and that ratio is called the constant of proportionality.

Here, if we divide c by b , we get

[tex]\frac{c}{b}=\frac{1.1\ b}{b}=\frac{1.1}{1}[/tex]

Thus the constant ratio of total cost 'c' to number of bottles'b' is  1.1 :1.

Thus, the constant of proportionality here= 1.1.
