The commission gary earns is proportional to the cost of the shoes he sells. gary earns 15% in commission for every $150 worth of shoes he sells. which equation give the total commission, c, gary will earn based on the cost, s, of the shoes he sells?

Thus, The required equation is :

Step-by-step explanation:

Minimum price to offer a commission = $150

Also, The rate of commission rate is given to be : 15%

So, Amount of commission earned per $150 = 15% of 150

                                                                          = 0.15 × 150 = $22.5

Now, C is the commission earned and S is the cost of shoes earned

Thus, The required equation is :

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
