Card 0 of 128
Susan went to a clearance sale and bought various items on sale. She saves 20% on a purse, retailing for $100. She saves 30% on a skirt that was marked down from a retail price of $40. She also bought a jacket that was on sale, and she spent a total of $150 . How much did the jacket retail for?
1. Her overall savings were 25% off the combined retail price of all three items.
2. Her discount on the jacket was $6 more than her savings on the skirt.

1. Her overall savings were 25% off the combined retail price of all three items.
2. Her discount on the jacket was $6 more than her savings on the skirt.
Using statement 1, it is easy to see how much the total retail amount should have been. The total retail amount discounted by 25% is the amount that Susan spent. So, we name a variable. Let x be the total retail amount. Then x - .25x = $122. We can rewrite this as x(1-.25) or x(.75)=150 thus, x = 200. So we subtract the known retail prices of the skirt and the purse to get the retail price of the jacket. So 200 - 100 - 40 = $60 is the retail price of the jacket.
Now, we should check statement 2. Using statement 2, we can calculate the savings we had on the jacket. We can first calculate how much we saved on the skirt. So 30% of the $40 retail price is $12. After we find this, we use the information from statement 2 to find the savings we had on the jacket. So $12 + $6 = $18 saved on the jacket.
Now, we need to figure out how much we spent on the jacket. We do this by taking the total amount we spent and subtracting the discounted price of the purse and the discounted price of the skirt. So, a $100 purse, at 20% off, is $80. We calculated our savings on the skirt earlier, so we know we spent $28 on the skirt. So $150 - $80 - $28 = $42.
Now combining these two pieces of information, we see we spent $42 and saved $18 so 42+18 = $60 retail price for the jacket.
We can see that either statement alone is sufficient to solve the problem.

In order to calculate the percent discount, both the original price and the sale price must be known. From statement 1, we know the sale price and with the additional information from statement 2, we can calculate the original price and then overall percent discount.

Susan went to a clearance sale and bought various items on sale. She saves 20% on a purse, retailing for $100. She saves 30% on a skirt that was marked down from a retail price of $40. She also bought a jacket that was on sale, and she spent a total of $150 . How much did the jacket retail for?
1. Her overall savings were 25% off the combined retail price of all three items.
2. Her discount on the jacket was $6 more than her savings on the skirt.

1. Her overall savings were 25% off the combined retail price of all three items.
2. Her discount on the jacket was $6 more than her savings on the skirt.
Using statement 1, it is easy to see how much the total retail amount should have been. The total retail amount discounted by 25% is the amount that Susan spent. So, we name a variable. Let x be the total retail amount. Then x - .25x = $122. We can rewrite this as x(1-.25) or x(.75)=150 thus, x = 200. So we subtract the known retail prices of the skirt and the purse to get the retail price of the jacket. So 200 - 100 - 40 = $60 is the retail price of the jacket.
Now, we should check statement 2. Using statement 2, we can calculate the savings we had on the jacket. We can first calculate how much we saved on the skirt. So 30% of the $40 retail price is $12. After we find this, we use the information from statement 2 to find the savings we had on the jacket. So $12 + $6 = $18 saved on the jacket.
Now, we need to figure out how much we spent on the jacket. We do this by taking the total amount we spent and subtracting the discounted price of the purse and the discounted price of the skirt. So, a $100 purse, at 20% off, is $80. We calculated our savings on the skirt earlier, so we know we spent $28 on the skirt. So $150 - $80 - $28 = $42.
Now combining these two pieces of information, we see we spent $42 and saved $18 so 42+18 = $60 retail price for the jacket.
We can see that either statement alone is sufficient to solve the problem.
