A washer and a dryer cost $744 combined, the washer costs $94 more than the dryer, what is the cost of the dryer?
sp2606 [1]
Answer: 325$

Explanation:
Assume: A is the cost of washer
And B is the cost of dryer

A+B = 744
And: A = B + 94$
We get:

B + 94$ + B = 744
2B + 94 = 744
2B = 650
B = 325

A shop recorded total sales of $2,000 on Monday. On Tuesday, its sales fell by 10%. On Wednesday, sales fell by another 20% comp
GenaCL600 [577]
The shop had $2,000 in sales on Monday. 
If it fell by 10% on Tuesday, then 2000 * 0.10 equals the percentage it dropped, so it dropped by $200. So they only had $1,800 in sales on Tues. 
If they fell by another 20% on Wednesday, 1,800 * 0.20 equals a $360 drop. Now we're at $1,440. 
The sales then increased by 25% of Monday's total # of sales. 25% of Monday's sales is 2,000 * 0.25 which equals a $500 increase. Now we're at $1,940. 
Now that we're done with everything, how far are we from the beginning? That's the net change. :) We began at $2,000 on Monday, and ended with $1,940 on Thursday. 2000 - 1940 is 60, so 60 = your net change. 

TLDR: Sold $2,000 on Mon, sold $1,800 on Tues, sold $1,440 on Wed, and then sold $1,940 on Thurs. The net change is $60.
