Question

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

What is the constant of proportionality?

Answer 1

In decimal form

Answer 2

Alright first we will need to find at least 3 values of each variable
C values 1, 2, 3
Now find b values with respect to the values of C that wr made means that we will substitute in the expression the values of C that we created and then solve for b
When C = 1 b will equal to 0.9090
When C = 2 b will equal to 1.8181
When C = 3 b will equal to 2.7272

So now we have
C: 1, 2, 3
B: 0.9090, 1.8181, 2.7272

Set the corresponding values as C/B
1/0.9090= 1.1
2/1.8181 = 1.1
3/2.7272 = 1.1
That's the constant of proportionality

Answer 3

BTW slope is always constan of proportionality.
