Step-by-step explanation:

Sorry if I’m wrong

Firstly, divide the tax rate by 100: 6/100 = 0.06 (tax rate as a decimal). Note: to easily divide by 100, just move the decimal point two spaces to the left.

Now, find the tax value by multiplying tax rate by the before tax price:

tax = 39.99 × 0.06

tax = 2.4 (tax value rouded to 2 decimals)

Add tax to the before tax price to get the final price:

The final price including tax = 39.99 + 2.4 = 42.39

Step-by-step explanation:

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.
