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 try to explain how you got the 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

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.

answer: 91

step-by-step explanation:

i got 86 for this

hope this !

if you need an explanation just ask
