A salesman bought a case of 48 backpack for 576 dollar. He sold,17 of them for $18 each and the rest sold to a department store for $25 each. How much was the salesman's profit.
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
