C=30+0.1N If the number of doughnuts in a batch is increased by 20 dougnuts, by how much will the cost of the batch increse?Answer by rajagopalan(158)   (Show Source): You can put this solution on YOUR website!cost of making each day's batch of N doughnuts=C=30+0.1N cost of making each day's batch of N+20 doughnuts=C=30+0.1(N+20) Increase in cost ( step2-step1=30+0.1(N+20) minus 30+0.1N =30+0.1N+(0.1*20)-30-0.1*N =30+0.1N+2-30-0.1N 30and -30 cancel 0.1N and -0.1N cancel Leaving 2 as remainder So Additional cost =2 Dollars The batch cost will increase by only 2 dollars okay
