The number of problems assigned as homework by a savvy math professor is a function of the length of the class on a particular d
ay, which is either 45 minutes, 90 minutes, or 135 minutes. He first multiplies the number of minutes by 4 and then divides that number by 9. Finally, he subtracts 12 from that amount. Which of the following functions best represents the number of math problems the professor assigns depending on the length of the class, t, in minutes?
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
