Pranav Olson · Answer 1

Total money spent is $11425 buying 75 animals

each chicken costs $65 so 50 costed the farmer $3250

each cow costs $45 so 15 cows costed the farmer $675

ducks purchased were 10

to find how much the ducks costs we will add the money spent the farmer and subtract it from the total amount spent.

11425-3250-675=$7500

10 ducks = $7500

so one duck costs 7500/10=$750

the price for each duck is $750
