A certain appliance uses w watts to run. If you run it for m minutes, and the cost per kilowatt-hour is c, the cost of running the appliance for m minutes is given by the formula (w(m/60))/1000 c. Find the cost of running an appliance that requires 500 watts for 25 minutes at a cost of $0.125 per kWh.

The cost for this appliance is $0.02604

Step-by-step explanation:

In order to solve this problem we need to apply the appliance's values to the provided formula as shown bellow:

cost = {[w*(m/60)]/1000}*c

cost = {[500*(25/60)]/1000}*0.125

cost = {[12500/60]/1000}*0.125

cost = {208.4/1000}*0.125

cost = 0.2084*0.125 = 0.02604

The cost for this appliance is $0.02604

$1.68

Step-by-step explanation:

If the function modelled for finding the cost of running the appliance for m minutes is given by the formula (w(m/60))/1000 c, and the following datas are given:

W = 500watts

m = 25minutes

c = cost per kWhr = $0.125

Cost of running an appliance that requires 500 watts for 25 minutes at a cost of $0.125 per kWh will be gotten by substituting the given data in the modelled function.

C= {500(25/60)}/1000 (0.125)

C =(500×0.42)/125

C = 210/125

C = $1.68

The cost of running the appliance will be $1.68

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
