$19,297 is invested, part at 13% and the rest at 8%. If the interest earned from the amount invested at 13% exceeds the interest earned from the amount invested at 8% by $777.58, how much is invested at each rate? (Round to two decimal places if necessary.)

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.

answer:   2 multiplied by x =24
