The cost of the dryer is 450
Step-by-step explanation:
Given : A washer and a dryer cost 821 combined.
The washer costs 79 less than the dryer.
To Find : The cost of dryer
Solution :
Let the cost of washer be x.
Let the cost of dryer be y.
Since we are given that their combined cost is 821 .
⇒ x+y = 821 (A)
We are also given that the washer costs 79 less than the dryer.
⇒x = y - 79 (B)
Solving A and B using substitution method .
Put value of x from (B) in (A)
⇒y -79 + y = 821
⇒2y -79 = 821
⇒2y = 821+79
⇒2y = 900
⇒y = 450
Thus , The cost of dryer 'y' is 450 .
Now putting this value in (B)
⇒x = 450-79
⇒x = 371
Thus , The cost of washer 'x' is 371 .
Hence The cost of dryer is 450
