A customer's monthly trash collection bill was $24.74. Due to a rate increase, her monthly bill is now $26.86. To the nearest tenth of a percent, by what percent did the amount of the customer's bill increase

8.57%

Step-by-step explanation:

Find increase:

26.86 - 24.74 = 2.12.

Find percentage:

= 0.08569118835 = 8.57%

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
