You need two equations to do this. The first is 2x+78=728. The other is x+78=y. In both equations "x" is equal to the price of the dryer and "y" is equal to the price of the washer. We know that the washer costs 78 more than the dryer. The math goes like this. 2x + 78 = 728 (first equation) 2x + 78 - 78 = 728 - 78 (subtract 78 from both sides) 2x = 650 (new equation) 2x / 2 = 650 / 2 (divide both sides by 2) x = 325 (dryer costs 325) Now we have a value for "x" and can complete the second equation x + 78 = y (second equation) 325 + 78 = y (substitute known value for x) 403 = y (washer costs 403) Now we check to make sure that we did it correctly x + y = 728 (dryer + washer = 728) 325 + 403 = 728 (substitute known values for x and y) 728 = 728 (we did it correctly) The dryer costs 325 and the washer costs 403

What is the cost to install a washer and dryer in an apartment?

The place you buy if from may do it for free, if new, or charge a small fee of $50-100.oo or less. If you hire a handy man that could vary. Both appliances come with directions how to hook up. The washer is easier than the dryer. You have a hot and cold line that connects from the washer to the spickets behind the washer, they are marked on the hoses. There is another hose that goes in the back of the washer that goes to the same spot that drains the water out on the spin cycle and a plug. On the dryer there is a plug and the vent hose that goes from the back of the dryer to the vent hole in the floor or wall. Takes less than an hour to do both. This is IF you have hook-ups already in place for a washer and dryer. If not, the costs are going to be a lot more significant. The cost depends on where you are putting the washer and dryer. If plumbing and electrical lines are close by it might run you about $400-500 for everything. (water lines to the washer, drain for the washer, electrical to the dryer and vent for dryer) However, it can be several hundred dollars more if you need to run plumbing and electrical lines significant distances (20 ft or more). To make it the cheapest possible, pick a location where water lines and an electrical box are less than 10 ft away. Also, if you do it yourself, you can save a lot of money and might only spend $100-200 in materials.


What determines whether a 100 watt light bulb costs more to use than a 1200 watt hair dryer costs to use?

The cost to use a device depends on its power consumption (wattage) and the time it is used. The 1200 watt hair dryer will cost more to use if it is used for a longer period of time compared to the 100 watt light bulb. Additionally, the cost of electricity per unit consumed (kilowatt-hour) will also affect the overall cost.


What determines whether a 100-w light bulb costs more to use than a 1200-w hair dryer costs to sue?

The cost of using a 100-watt light bulb versus a 1200-watt hair dryer primarily depends on their power consumption and usage duration. The energy cost is calculated by multiplying the wattage by the hours of use and the electricity rate per kilowatt-hour. If the hair dryer is used for a short period, it may cost less overall despite its higher wattage, while the light bulb, used for longer durations, could lead to higher cumulative costs. Therefore, the total cost is influenced by the wattage, usage time, and local electricity rates.
