Original price: $45.00; markdown: 22%

$35.10

Step-by-step explanation:

Original price = $45.00

Markdown = 22%

Therefore, 22% × 45.00

= × 45.00

= 0.22 × 45.00

= $9.9

Now subtract $9.90 from $45.00

= $45.00 - $9.90 = $35.10

$35.10 is the answer.

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.
