Now ! love 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.

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.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

16
