he gained 15% on 3/4 of the shipment.
he lost 10% on 1/4 of the shipment.
let x = the cost of the shipment.
he gained 15% on 3/4 of the shipment.
he lost 10% on 1/4 of the shipment.
his net gain was 15% * 3/4 minus 10% * 1/4 = 8.75%.
let's see if this makes sense.
assume his cost was 1000 dollars.
3/4 of the shipment would cost 750 dollars and 1/4 of the shipment would cost 250 dollars.
he made 15% on 3/4 of the shipment, therefore he made 15% of 750 = 112.5 dollars.
he lost 10% on 1/4 of the shipment, therefore he lost 10% of 250 = 25 dollars.
his net gain was 112.5 minus 25 = 87.5
his net gain overall was 87.5 / 1000 = .0875 * 100 = 8.75% of the cost.
