Can anyone help with these hard math questions?

1.Ben sold 82 of his baseball cards. If eighty-two cards represented 12 1/2% of his total collection, how many baseball cards did Ben have?

2. A flower arrangement for a bridal shower is made up of roses and carnations. The arrangement is made up of 60 percent roses and 40 percent carnations. There are a total of 25 flowers in the arrangement. How many flowers are roses and how many are carnations?

3. Larry bought a dump truck for $17,000 and sold it for $19,720. What was the percent of profit?

4. Shari bought a house for $93,000. To date, the house increased in value by 5 percent. What is the amount of increase? Also, what is the new price of the house?

5. An end of summer sale ad shows that if you buy a $1,695 red cedar patio furniture set AND a $249 umbrella, you will receive a 45 percent discount on both items. What is the amount discounted for both items? Also, what is the sale price if both items are purchased?

Can anyone help with these hard math questions?
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
