1. 656 cards (100/12.5*82)


2. 15 roses/10 carnations


3. 14.8%


4. Increase=$4,650 new price=$97,650


5. Discount=$874.80 Sale price=$1,069.20
Reply:1. 82/.125 = 656 cards





2. 25 * .6 = 15 roses


25 * .4 = 10 carnations





3. 19720/17000 = 1.16 = 116%





4. 93000* 1.05 = 97650 4650 dollar increase





5. 1695 + 249 = 1944


1944 * .45 = 874.8 discounted off


1069.2 is discounted price
Reply:1. 12.5 % is written as 0.125


So 0.125 * TOTAL = 82 now solve for TOTAL


TOTAL = 82 / 0.125


TOTAL = 656





2. 60% roses, is 0.6 * 25 = 15


40% carnations is 0.4 * 25 = 10





3. Profit % = (selling price - buying price) / buying price


Profit % = (19720 - 17000)/ 17000


Profit % = 0.16


0.16 is 16% so profit increase is %16





4. amount of increase is price * value increase% = amount increased


93000 * 0.05 = 4650


new price of house = old price + value amount increase


New price = 93000 + 4650


New price = $97650





5. so the subtotal is 1695 + 249


subtotal 1944





45% discount 0.45 * 1944


amount discounted 874.80





the purchase price of both items is then subtotal - discounts


purchase price = 1069.20


and sale price of each item is:


patio furniture sale price = 1695 - (0.45 * 1695)


= $932.25


umbrella sale price = 249 - (0.45*249)


= $136.95
