The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
First you have to subtract 59$ from 61.36 which will give you 2.36.Then you have to multiply 0.02 to 59 which equals 1.18.Then you multiply 0.04 by 59 which will give you the answer.Hope this helps!!!Your answer should be 0.04!!!Please Mark brainliest!!!!!
