You anticipated a large demand of toys and increased you invententory by of 1600 by 5%. You were able to sell 85% of your inventory

Question

How many toys will remain?

Answer 1

Just looking at your other problem and what I'm guessing is some methods they may want used, I'm going to toss in this alternative.

 

If you add 5% to something, then you have 105% of the original amount.  So if you directly multiply 1600 x 105% = 1600 x 1.05, you'll get directly to the total that was available in inventory.

 

Then if you sold 85%, you have 15% left over.  So you can get directly to that answer by multiplying the 1680 x .15 = amount that remains.

 

Again, I'm tossing that in because of what I've seen in your other problems.  But even so, if you can understand this method, it's actually faster with less calculations.

Answer 2

You have some errors in the question but from what I understand initial there are 1600 toys, you increase them by 5%, and then sell 85%. how many toys remain?  So 1600* 5% increase= 80, so he bought 80 more toys, 1600+80= 1680 toys in inventory. He sells 85% of them, so 1680*85%= 1428, so he sold 1428 toys. So how many remain= toys in inventory- amount sold= 1680-1428=252. So 252 toy will remain.
