Question 202756
Here is my try:
w+d=841
w+91+d=841<br>
The first equation is good. The second equation ... not so much.<br>
The second equation should state the relationship between the cost of the dryer and washer. Since the "washer costs $91 more than the dryer" we can use:
w=91+d<br>
So our two equations are:
w+d=841
w=91+d
Using the second equation, since it is already solved for w, we will substitute for w into the first equation:
(91+d)+d=841
Simplifying we get:
91 + 2d = 841
Subtracting 91 from both sides:
2d = 750
Dividing both sides by 2:
d = 375
So the dryer costs $375. To find the cost of the washer we can substitute this number for d in one of the 2 equations. Using the second equation we get:
w = (375) + 91
Adding we get:
w = 466
So the washer costs $466
