Suzanne helped write out diplomas. Issuance its first took 3 minutes, each next 2.3 minutes. How much time it will take to write out n=16 diplomas (including the first), write out this pace?


x =  37.5 min


x=3+2.3(n1)=3+2.3(161)=37.5  min x = 3+2.3\cdot (n-1) = 3+2.3\cdot (16-1) = 37.5 \ \text{ min }

Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
