First, let's find out how many he sold to the department store: 48 − 17 = 31
Now, we know he sold 17 for $18, let's get that total: 17 ∗ 18 = 306
Next, let's figure up how much he made from the department store: 31 ∗ 25 = 775
So, in total he made: 306 + 775 = 1081
Minus the initial cost of the backpacks, gives a profit of: 1081 − 576 = 505
To get the answer we have to calculate income and subtract 576 from it. He sold 17 bp for 18 so 17 ∗ 18 = 306 We know that rest (48-17=31) he sold for 25 31 ∗ 25 = 775 Now we can add income 306+775=1081. Finally we can find profit 1081-576=505$ - its the result
The salesman's profit from selling the backpacks is $505 after selling 17 for $18 each and 31 for $25 each, while the initial cost of the backpacks was $576.
